Not a GameStop employee here, but the friend of a former one.
They'd just gotten a shipment of Pop Vinyl figures, and I was there looking for some particular ones that were a bit harder to get my hands on. Dr Who, Kingdom Hearts, a few blank ones for customs. Stuff like that.
In walks a few kids. No problem. Me and my friend, the actual worker here, converse. Lets point it out. My friend is an 8/10 girl, but I'm gay, so she was always open to talking to me. Manager knows me too, so nothing was wrong with us chatting. It wasn't busy, and I'm a paying customer.
The kids looked around, picked out a few items, and seemed to talk amongst themselves. One of them seems to be looking for something, so my friend, being the great person she is, goes up to help him. She asks what he was looking for. Kid #2, the one looking for something, asks where the Switch games are. Friends points them out. Kid #1, who was behind her now.. slaps her ass.
Needless to say, parents were called, and they were forced out. My friend's still working there, but she tends to not leave the front desk as often as she would before.
