Lol. That's too funny, this happens to me all the time too. I am a Dental Assistant, and wear scrubs everyday and my name tag. My office is located in a mall, and whenever I am on lunch, or on a break, I go into various stores, and because I'm wearing a uniform, I always get approached for help, information, etc. since I've worked in the mall for 15 years, I pretty much know where all the washrooms, stores, and food court is, and other information. I'll usually say sorry I don't work here, I'm just on my break, but I can answer your question, then I will direct them to where they want to go. They usually get all flustered, and say sorry, but I say it's okay, and we always get a chuckle out of it.
