There is always one member of a table of diners who seems intent on making a waiter's life more difficult than it should be! The waiter has noted down everyone's order as is about to go the kitchen, when you call him back. "Excuse me, waiter! "Yes madam?" "Could we start again? I'll have steak and chips."

Sometimes it's hard to decide what dish you want in a restaurant and as long as you are polite then changing your mind is not a problem usually so always add please to be nice and polite

If you ordered something at a restaurant and the waiter/waitress had already written the order, you definitely can politely ask him/her to cancel it if you suddenly change your mind and would like to eat something else. It often does happen that after perusing through the menu, you choose a dish that you really didn't mean to order and immediately decide to order a different one. You are perfectly in order to ask the waiter/waitress to cancel it and replace it with what you really would like to eat. You may politely ask the waiter/waitress as follows: Please cancel that order because I would like to have something else. Apologies for the inconvenience. or Oh, wait a minute. Will you please cancel that order and give me pasta instead? or Sorry waiter/waitress, please cancel that order and give me pasta intead.

Both of these options show that you have change your mind. You can add pleasantries such as 'I am sorry' and 'please' wherever you need them. E.g .'Actually, I think i want something different, sorry!' or 'I made a mistake, could I have this instead please?'
