What Do You Do In This Situation?

Here is a good question for you waiters out there.

I was once told that when you give the bill to someone and after you have run it through the credit card machine that when you bring it back , instead of just dropping it off to be signed and go somewhere else you should just stand there and wait till that person fills it out. By standing there waiting for the guest to fill out the tip and total portion they will tip you more because you are right there waiting. They will feel a bit nervous with you standing there in other words.

On a night like this I was tempted to try it out since the tips were garbage tonight.

What do you think out there? Stand and wait , or just drop off the credit card to them and pick it up after?
