What "type" of the restaurant you work for? I mean, Hongkongese-western style, Caucasian style, or Chinese....etc?

Anyways, let the customers know in advance whenever there is a charge on anything they seem don't know or not officially on the menu.

Same as I ask for XO sauce at dim sum restaurants. I ask: "Do you have XO sauce please?" If the server answers: "Yes, we do.", and then he/she gives me one, I won't expect to pay for it cuz he/she didn't mention. But if he/she answers: "Oh yes, it's $3 per dish.", then it's my decision to order it or not and of course I understand that I have to pay for it.

If a customer goes to a HKese-western restaurant and order a cup/glass of hot water, I believe nobody would charge for it. But then the cheap customer ask for some slices of lemon and put together with the free sugar which was already on the table setting to make a self-made "hot lemon water", I think he/she will be charged! (the fact is, no server will give him/her free lemon in the first place)

Next time, tell your valuable customers: "Sorry sir/madam, we don't have loose slices of lemon, but a cup/pot of lemon with water/tea is $3.50. How many would you like?"
