Breh that crazy, foul, vile, neanderthal cracka would have grabbed a handful of her fecal matter and smeared it all over you had you dared violate her personal space.
Unless you're willing to go home with the aroma of middle-aged, unhinged white woman shıt all over you, penetrating your nostrils with every inhale, tasting it all in your mouth every time you speak, having that smell stuck on your tongue, and probably being stuck in the ridges under your kicks, I don't think any of us would have done anything different than what the clerk did in that vid.
ESPECIALLY if you're not the owner of the establishment.
My apologies for the gross and graphic descriptions, but just wanted to make sure you knew what you'd be stepping into (probably literally) before the Billy Badass fantasies set in.
Unless you're THAT crazy, stay the fukk away from crazy.
