How to Annoy other Kroger customers

I found it funny, though I don't know that the lady monitoring the self-pay registers or the other customers did. It was close to hubby's pay day, I didn't really have any cash. I'd fished out enough quarters to pay for parking at the Neurologists office with some left over. We were out of milk and cereal, so on the way home I stopped by Kroger just for that. I fed the poor machine $9 worth of quarters, one dime and 16 pennies. No one said anything to me about it, I just found it funny.
