Disgusting, yes. Especially considering that floor looks wet. I don’t care if they just mopped, that’s still nasty.
The real question though, is would I still eat it…and that answer is a resounding “Eh…probably.” Checkers is the shit and a meal there is like $10, go take a peek at my bank account and you’ll see that I don’t have room to waste $10. Maybe just take some immune system-boosting vitamins beforehand and it’ll be fine…or I’ll die of hepatitis. But yeah I’d still eat that.
