7-Eleven at 5020 John R Road, Troy, Michigan.

The absolute worst management, extremely rude. You can tell they never clean the inside of the slushy machine just by the way it taste. When I bought a frozen coke all I can taste in it is the other fruity flavor slushys that where next to the frozen coke. If I get a coke then I expected it to taste like coke. That just tells me you don't clean your slushy machines. This place is trash, especially the management!
