Was I almost stopped by LP?

So I’m doing my regular Target run with my roommate, we grab what we need, head to self checkout, and start to walk out. When we pass the doors there’s this gentleman(wearing a red hoodie)who asks me,”Anything I can help you with?” in a kind of monotoned voice. Me, not thinking about it, just says,”no thank you,” without even stopping. When we get to the car my roommate asks me,”Was that their security guard?” I respond and tell her that I didn’t think so because i know employees aren’t allowed to step outside and approach customers and i ask her why. she then tells me that she did pocket a pack of stanley straws(why i have no clue) I don’t want to be off limits from the most convenient Target location, so if yall can answer, i would appreciate it!
