"A word of caution: when paying, be sure to provide the exact amount you owe and avoid requesting specific change, as this can lead to confusion. My total bill came to $18.61. I handed the cashier a $20 bill and asked her to take $10 from it (either giving me a $10 bill or two $5 bills), while I would pay the remaining $8 in singles and the 61 cents in coins. I wanted to do this because I had a lot of singles I wanted to use up. Instead of following my request, the cashier returned the change from my $20 bill, giving me $1.39, and insisted she couldn't assist because she had already counted out the change. I tried to explain my intention to her, but despite my efforts, she struggled to grasp the concept. Eventually, she called over another cashier and then a third, but none of them seemed to comprehend my simple request. One of them even claimed to be very good with numbers! Frustrated, I decided to drop the matter and left, feeling bewildered by their attitude and inability to understand such a straightforward request."
