Two true stories that happened to me---
Bank--I had a business deposit with less than $2.00in change. None of the coins made a roll. The teller said, "We don't take coins." what?? you're a bank!!
Fabric shop--I asked the cutter (a 18-19 yr old boy) for 1 1/3 yd. he said he couldn't cut that. He could not figure out how much that was because it wasn't marked on his yardstick. I bought 1 1/2 yd instead. He must have been absent in the third grade when fractions were presented.
