Line Printer Puns

So for background, I work at McDonald's. I have to scan every Euro Bill 50 € and up.

So one day a dad comes in with his two little daughters. He places his order and hands me a 50 € bill. I scan it and scan it again and the machine won't recognize its validity, when the dad says:'That's odd, I JUST changed my printer's toner' Daughters facepalm other dads in line nod

Waiting for the printer, in the copy room, to finish my job and a couple of others. Some guy walks in and asks, "What's the queue look like?"

"Well, it's a bit like an 'O,' but with a little line at the bottom."

He more or less turned around on the spot and walked out.
