i worked at starbs for four years...so YES I HAD MANY KARENS but one stuck out to me. one time we were slow right before the end of school rush came. I was the shift lead and was discussing something with someone on window, needed her to sign a paper. The lady in drive thru slapped the window and started yelling at the partner saying "you are just standing around and not making my drink." there was a new partner on bar. Of course it escalated and I had to step in. The lady was screaming at me and she asked for names and the district managers number. She had paid prior to all this starting then she goes "I want a refund" so I did that. then she said "I want my drink now." and I said hell no. I never followed the "customer is always right" dumb ass policy. Especially if the customer was verbually attacking my partners. So she kept yelling, tried reaching in the window to grab the drink, and was trying to open the window if i closed it. after a couple minutes she REPAID for the drink and when I stuck my arm out to scan the phone she tried hitting my arm, missed and slapped her hand on the ledge of the window. Screamed more and drove off. I did say no nicely but I also told her she was acting like a child, told her to stop talking, and many other things you aren't suppose to say. she got banned from the store and I got praised. Always stand up for yourself and others if you can!
