>I would tell them I wasn't working there but one refused to believe me, she said I was lying because I just didn't want to do the work to check for her.
I had this happen once in a big box store. Not only did she not believe me, after repeating it a few times she started to get belligerent and called me a lazy piece of shit and that the customer is always right.
I usually try to be pretty docile, especially on business trips but I lost it at that.
I told her to shut the fuck up, I'm not a fucking employee, that I won't be fucking spoken to like that by some dumbass mouthbreathing moron and to get the fuck away from me. She stormed off yelling about getting a manager (??)
I grabbed what I came for (a mouse - forgot mine before flying and decided to get a cheap one IRL since this was pre-Amazon-locker.)
I ran into her at the checkouts, yelling. She pointed at me, frothing with rage, yelling about how disrespectful I was and that I was lucky she didn't slap me (!) and she wants me fired.
So of course, I decided to work that angle: told the manager I repeatedly told her I don't work here, that she swore at me, is now threatening me, and if he doesn't remove her from the store I will be calling the police to do his job for him.
Luckily the problem solved itself - she let out a shriek and puttered her trunklike legs out the door. (Maybe she had warrants?)
