I think I just saw an Alien

I think I just saw an alien.  Not a UFO or a slimy mutant.  But the kind of alien, like the aliens in disguise like in the Men In Black movies.  They look just like humans but do weird shit that humans don't usually do. 

There was some commotion, a sound of crinkling plastic wrappers and sort of grunting coming from the back of the gas station mini mart while I was picking out something to drink.  Then a guy emerged from the scuffle. He was old, smallish build, kinda unkempt, needed a shave.  His messy salty hair covered his face but revealing thick rimmed glasses like you get at Walgreens.

Nothing that outright screamed alien, except he was carrying a stack, two hands holding probably every prepackaged microwave hamburger in the food cooler.  Which is weird but not alien status.  What made me certain that he was not from this world was when he started microwaving them all in the store. 

Who the fuck eats 8 gas station hamburgers at once... Inside the gas station?

That dude was a fucking alien.
