Turning The Stupid Up To Eleven, Part 3

I work in the office that manages an apartment complex. A resident hasn’t made his payments for a while, so he has been making random payments throughout one month to try and catch up.

This resident storms into the office.

Resident: *Demanding tone* “Calculate how much I’ve paid so far for my rent payment!”

After I’ve calculated everything:

Me: “Sir, as of today, you have paid a total of eleven hundred dollars.”

He has a look of success on his face and starts laughing.

Resident: “I knew it! You’re trying to rip me off! Here are all of my receipts! Add it up again!”

I add up his receipts.

Me: “Once again, sir, you have paid a total of eleven hundred dollars.”

Resident: “Wow. You guys are really something else. I knew you were screwing me over. I have paid a total of one thousand one hundred dollars! Add it again!”

I thought for a moment that he was messing with me. He was not.
