Are You Smoking???

I was outside a grocery store that has a coffee shop inside of it, so I got my coffee and sat outside in the non-smoking section to vape. An employee comes out and looks confusedly at me and says "Is someone smoking out here?" Nope, nobody smoking here. The employee shrugs and says, "oh okay, we got a complaint that someone was smoking out here, sorry." When she went back inside I continued vaping and that was that. Some people just like to complain, to show they have power over other people I suppose.
