I was once in a store I used to work at, but had quit and was just there shopping. I guess some lady recognized me and started asking me questions, but I told her I didn't work there. She insisted I in fact did and kept asking me questions. I informed her I was an employee but no longer was so I couldn't help her. She demands to speak to my manager, I said "what manager?" A former co-worker comes over and tells her that, indeed, I no longer work there and offers to help her but she demands that I help her. I just turn around and go check out, and she's screaming at me from the aisles as this guy keeps telling her I don't work there anymore.

Later my buddy who still worked there called and informed me she filed a complaint with management, who again tried to explain I was no longer an employee of their company.
