True story.
I've a friend who works in a grocery store. This store has a little coffee area, where they make lattes and such, fill growlers with beer, and the make the southern staple - sweet tea, and sell it by the gallon.
Black female, late 40's, buys said sweet tea, takes it home, brings it back the next day HALF GONE, and wants her money back because it wasn't sweet enough.
SHE DOES THIS 6 TIMES.
Finally they tell her that maybe she should try some other tea, since she obviously doesn't like theirs.
She accuses the employee of being a racist, and files a complaint with corporate about the racism the store employees exhibit.
Nothing happens to any employee.
