Most mornings I do a shop for the day / week. I always pick up a bottle of wine or a few beers along the way.
This morning I went to the chainstore (my local), to buy wine. Later today I went back to pick up a few more bottles. The cashier that served me in the morning was standing next to the cashier that was serving me later today. She told her that I was most likely drunk and they called their manager to decide what to do. I was eventually served and left but I asked the manager why her colleague had deemed me drunk. She didn't have an answer. I do look very young so being ID'd is not my concern but whispering among themselves that I'm drunk has really put my hackles up.
