I sent an employee at JoAnn's home one day. She loved to get another employee in the corner and visit rather than work. Needless to say, the word was passed and it didn't happen on my shift after that. Chatting with fellow employees during the course of a day - yes, of course. Standing around and talking - not on my clock.
I'm very sorry you had this experience. I would have waited on you for as long as it took just to hear your lovely accent.
