レストランでお客様が食事を終えてて、お皿を下げたいときって英語でなんて言うの？

In my experience servers usually ask if I am finished and then proceed to clear the plates if I say yes. You can also be more direct and just ask if you can clear the plates.

Using 'have you finished' can be short and informal, 'have you finished your meals' sounds much more polite. 'If you guys have finished eating, may i take away your plates?' Using the word 'if' and 'may' take away any pressure you might put on the customer.

One way of knowing that customers have finished eating is the arrangement of their knife and fork on the plate. If the knife and fork are together in the middle of the plate (12 o'clock) then they have finished eating. Not everyone follows these principles but it is a good indication. Otherwise you can ask politely to remove their plates or 'clear the table'. I hope this helps!

It is good to say "excuse me" to the customer if you just walked up to the table because you may be interrupting a conversation or activity. You could then simply ask, "are you finished" or "can I take this?" To not make the customer feel rushed, you could say, "Can I take this out of your way" or "would you like for me to take this out of your way?"This shows that you are concerned about the customer's comfort.

These questions are both good because they allow the customer to decide what you can take from their table. It's never good to assume that the customer has finished with their plates or silverware so these questions help you avoid taking something that the customer is still using or would like to use. By using the question, "Is there anything that I could get out of your way?", you are letting the customer know that you want to help them make more space on their table so they will be more comfortable.

If you want to take away everything from the table you could say, 'Shall I clear the table?' If you only want to take the plates, you should say, 'Shall I take the plates?' the customers may wish to continue with their drinks. To clear up = clear away the used items on the table.

Can I get those for you? - "to get" in this case means to take; "for you" means on your behalf/to help you out Are you finished with these? - Before you take the dishes from the customers, it's appropriate to ask if they're finished eating the food on the plate because maybe there is still something on the plate that they want to eat.

To ask a customer if you can take away their plates, you can say: "Have you finished?" "May I take your plates?" "May I take this for you?"

The phrase 'clear the table' used in the first request means taking away everything that is no longer needed on the table. The phrase 'if you are done' means 'if you have finished', and in this case, 'finished eating the meal'. In the second request, you were succinct so that the customer understood you clearly. So, you may say: May I clear the table if you are done? or May I take the plates if you have finished your meal?
