About an hour ago, I went to my university's campus convenience store to buy an energy drink. When I got to the counter, the total came to $3.24, and I took out a ten dollar bill and gave it to the cashier.
The cashier had just popped out the drawer when I said, "Oh, and here's twenty-four cents", two dimes and four pennies I'd found in my pocket. She looked at it and said, "I can't take it, the drawer'll come up short".
I looked and she hadn't even put the ten I'd handed her into the drawer yet. I asked, "How would it come up short?" She said something like, "If I take it out, and then I...it's complicated."
Since it wasn't really a big deal either way, I just kept my change and took the $6.76 she gave me.
I've worked four retail jobs before, and I've never worked a register where it mattered what kind of change you gave back. I could understand if she was low on singles or something (though that doesn't explain why she said the drawer would be short).
