> I've heard a few times that leaving a penny heads-up on the table is supposed to indicate good service. Does anyone actually do that? I sometimes find head-sup pennies on my tables when I bus them, but for some reasin I'm inclined to think that people just left them by accident.

I may be able to take a stab at it: it may be related to the old thing about it being good luck to pick up a penny if it's heads up, and bad if it's tails.

That said, we usually leave a little more than the regular, rounded to the nearest quarter or possibly the nearest dollar.
