Came up to my register and asked for the price of a protein bar. Every item in the store had a physical price tag, because we didn't have scanners at the register. I took it from her, flipped it over, and let her know it was $2.49 before tax. She asked me how much the case would be. Normally we did discounts for cases, but they had to be ordered ahead of time, so I started explaining we couldn't do a discount unless - she cut me off aggressively and hissed "I didn't ask for a discount." So I typed in $2.49 x 12, added tax, and told her the final price. She stared me down for a few minutes before asking me to get my manager. Once my manager arrived she spent literally 10 minutes tearing into me, describing me as the least helpful person ever, talking about my bad attitude, complaining about how awful and rude I was, etc. etc. etc. I was working nearly full time (35.5 hours per week) and commuting to a school over an hour away four days a week. This lady took the time out of her day to break me down to the point I started crying. Thanks Karen, I still remember you - hope you enjoyed your [friggin] protein bar.
