お酒を持ち込んで勝手に飲んでいるお客さん

Me: Excuse me, are you drinking your own drinks?
Customer: Yeah, why not?

Me: Sorry it is not permitted in the restaurant. Could you please put it away now?
Customer: Ahh ok.
Me: Thanks.

(After a few minutes.)

Customer: ... (customer is ignoring my warning and still drinking same alcohol.)
Me: Excuse me, I told you before.
Customer: Ahhh I know, I'll finish it up.
Me: Well, I'll grab beverage menu for you if you want to drink. Though if you continue to drink your alcohol here I'll have to call a bouncer.
Customer: Ah, no no no no, I stop now. I promise.
Me: Thanks. Sigh.

テーブルや椅子を動かすお客さん

(On the floor)

Customers are moving some tables and chairs to make their table and obstruct a hall way.
 
Me: Excuse me guys, how many people do you have?
Customer: We are four now but our friends are coming soon. There'll be nine of us.
Me: Nine. Well, I'm sorry this here is our hall way. We need to keep it clear, so you guys can't make a table here.
Customer: Ah really? Do you have a table for us?
Me: Sorry we don't have space to make you guys a table at the moment. You can take a seat separately or you can wait until some other customers leave.
Customer: Ahh noo. How long a wait do you think that will be?
Me: One of the table's over there are just grabbing their bill, so it shouldn't be long.
Customer: Really? All right. We'll wait. 
Me: Could you please sit here and wait for a while till we call you guys?
Customer: Thanks.

私のバッド・デイ

Me: Are you ready to order?
Customer: Yes I am. Can I have a caesar salad?
Me: One caesar salad, anything else?
Customer: That's all.
Me: Thank you.

(After couple of minutes.)

Me: Excuse me, here you are.
Customer: ... Excuse me, I ordered a chicken caesar salad. Where is the chicken?
Me: Ah really?
Customer: Yes, I ordered a chicken caesar.
Me: Sorry I thought you ordered a plain caesar salad. I'll ask our chef to make a chicken caesar right away.
Customer: Yes please.

(In the kitchen.)

Me: Excuse me, Maybe I heard wrong, this customer says they ordered a chicken caesar. Can you make it as soon as possible?
Chef: Ah really? No worries, it'll be about five minutes.
Me: Thank you very much.

(After a couple of minutes.)

Me: Excuse me, thank you for waiting. Here is your chicken caesar. Enjoy your meal.
Customer: Thank you.



Me: Are you guys ready to order?
CustomerA: Yes we are. Can I have a schnitzel?
Me: Yes of course you can.
CustomerB: Can I have the same?
CustomerC: Me too.
Me: Three schnitzels, anything else?
CustomerA: That's all.
Me: Thank you.

...

Me: Excuse me, three schnitzels.
CustomerA: Excuse me, I wanted chips and salad on this order. I don't want to have vegetables and potatoes. 
Me: Ah schnitzel comes with vegetables and potatoes. That's on the menu here.
CustomerA: Really? I'm not going to take it.
CustomerB: Ahh no chips and salad?
CustomerC: I don't want to have this.
Me: Ok, I'll ask our manager if you can change your orders.
CustomerA: Please.

(In the kitchen.)

Chef: (look at me with the schnitzels still on my arms.) You forgot their number did you?
Me: No I still remember their table number but I have another problem.
Jack: (Manager, saw me on the floor and just came to the kitchen.) What's wrong, Cyara?
Me: Sorry they want to have chips and salad instead of vegs and potatoes.
Chef: Are you serious? All of the schnitzels???
Me: Yeah, they didn't tell me when I took their order. :(
Chef: Ahh nooo! They should have told you before this. They cannot be cancelled. It's not on the menu. Sigh.
Me: Sorry I should have double checked.
Jack: Ahh, noooooo, but that's fine. It's too hard to ask each time when you take an order especially since it is written on the menu. We'll just remake their meals.
Chef: Sigh. ...Three schnitzels with chips and salad please!!! (called to other chefs.)
Me: Thank you very much.
Chef: No worries, sigh.

...


(After that.)

Me: Excuse me, three schnitzels with chips and salad.
CustomerA: Thanks. That's what I wanted to have.
CustomerB: Ta.
CustomerC: Cheers.

お客さんの好みにあわないケース

Me: May I help you?
Customer: Do you have olive oil?  
Me: Yes we have. I'll go get for you right away.
Customer: Thanks.
Me: Here you are.
Customer: Oh, thank you. (Customer takes a sniff the olive oil in the bottle and quickly gives a scowl of disapproval.)
Me: Is there anything the matter?
Customer: Hmm, is this olive oil?
Me: Yes it's olive oil.
Customer: Nooooo it's not olive oil. Smells like vegetable oil.
Me: This morning I filled the bottle with fresh olive oil. I'm sure this is Australian extra virgin olive oil.
Customer: Are you serious?
Me: Yeah I'm serious.
Customer: Hmm, I don't think I want to have it. I think your restaurant should get a better brand of olive oil. This is not good quality.
Me: I'm sorry, that's all we have.
Customer: Sigh. That sucks.
