I don't get paid to flirt with you.
Recent posts on the whole “guys flirting with the cashier and not taking the hint” thing reminded me of the worst experience I’ve had with this situation.
One of my first jobs when I was still a minor, this guy came up and kept trying to ask me personal information and trying to ask me out. I was VISIBLY uncomfortable with this guy that looked twice my dad’s age, and when I made a point to tell him not only am I uncomfortable but I’m also A MINOR, he then decided to park his ass near my work station and yell at everyone that came by me that I was rude and nasty and mean and deserved to be fired and a bunch of other bs.
At the place I worked at I didn’t have a way to call another employee or security over to help me with the guy so I had to deal with him spouting nonsense and scaring away my nice customers for almost 10 minutes before a really nice guest offered to find the nearest security person for me. They eventually returned with a security person and one of my managers and pushed the guy out.
