People that buy $50 in groceries, when the store is very busy, the lines very long...and then pay for it in change. Not even quarters or rolled coins; in small, loose change. And then argue that the cashier counted incorrectly because they counted twenty five cents more. And then when the cashier recounts the change and comes up with the same figure, they argue that the cashier must have dropped that twenty five cents somewhere, because she was being careless.
If I needed to raid my piggy bank to go shopping, I would either use a coin counting machine at the bank, or at the very least not do it during 'rush hour' traffic.
edit: man, but that felt goood to get off my chest.
