I just went to McDonald's for a drink. My change was $2.64 and they were out of dollars in the register. So the cashier sent a manager for ones. In the meantime, as the line grew behind me, I said, "I'll take quarters for my change, no prob."
With a stricken look on her face she began counting out coins for my change. After several seconds she looked at me very earnestly and said,"can we just wait for the ones? I'm bad at counting."
