I work in a mall at a warehouse of designer shoes. One time I was with my friend shopping there & a customer came up & asked me if I worked there. I stupidly said "yes but I'm not on a shift right now" & they tried to make me get a bunch of shoes "from the back" & be their personal shopper. I repeated that I wasn't working and directed her to one of my coworkers & they asked for my manager? I hadn't even worked on the floor at this point so it's not like they could recognize me either.
