How do you tip a waiter when you pay by credit card?

Question

Thanks to all who answered. I couldn't decide because there were so many good answers so I have put it to a vote.

Answer 1

Fill in the "tip" line, and add the price and tip together in the "total" line.

Answer 2

Put the tip in the tip line of your credit card receipt when you're signing for it.

You can always just tip him/her cash and leave the tip line blank.

Answer 3

Either tip the waiter by cash or fill in the tip line.

Answer 4

i prefer to tip in cash to the waiter. when tip is added in credit card payment, i sometimes wonder if the tip really reaches the waiter or is kept by the manager on the counter.

Answer 5

sometimes i add tip to receipt and other times I tip in cash usually 18%

Answer 6

Either at least 15% on the credit card receipt, or if you really want to be nice...give them a cash tip because they don't have to pay taxes on it!

Answer 7

fill in the tip line. after that evening, someone at the restaurant runs the credit card authorizations and the final amount is charged. (i believe that is how it works)

If you like the person, leave a cash tip.

Answer 8

when you get the receipt, you write down how much you want to tip them! that's all or if you have something else in mind you want to tip him different

Answer 9

Included in the bills or give them cash,whichever conviniences to..

Answer 10

when you get the receipt, you write down how much you want to tip them! that's all!
