Report them to corporate, they listen. The 7/11 around the corner used to let the homeless sit out front and harass everyone. Few emails to corporate and the loiters are now gone.
Now before anyone cries like a wimp, they were super aggressive. I'm a big scary guy and they would fuck with me. Forget it if your a woman, it was so bad almost no one would go there and hit the other mart that was more expensive.
I would send a check, its more work for them in the end.
