I was discriminated against at Target for being in a well known rock band

I'm a man in my early 60s and while I won't reveal my actual identity I was in a high profile rock band that once opened for Twisted Sister in the 80s.

I was at the Target off 117th when I tried to buy a cola and wouldn't you know it, card declined. I explained to the clerk that I needed this cola and he basically gave me the runaround.

Eventually I was told to leave and I know they recognized me from my performances as one of our shows is on Youtube and I mentioned my name to them earlier in case they didn't know. There was no need to be this hostile towards me and yes I did some bad things at shows, mainly our bassist though.

I'm calling for a boycott of this Target until they issue a statement
