If I put it on the counter I try to slide it over to where the cashier can reach it. We aren't animals. People need to learn to slide cash into reasonable vectors of attainment. In fact you should put a sign up requesting customers do that using those exact words.

EDIT: Some bank cards have credit or debit options, if you want debit you put in a pin, if you want credit you cancel and hit credit and sign it electronically on the touch screen thingy (which is actually more like a check in a way, so it actually makes more sense for a check card to sign, but yeah, they also have the pin option). Although I've noticed at gas stations if you want credit you type in your zip code as opposed to signing with a touch screen.

I'm actually not sure of the difference between the two since it's all coming out of your bank account, although with at least one of my bank cards if you choose credit you get cash back but if you just do debit you don't, and I have no idea how it's "credit" because it's debited from your bank account just like with debit. Maybe there is a delay of sorts if you just sign, kind of like with a check or something...
