I usually don’t watch such videos but I watched this one. The very definition of “uncivilized”: no regard for the staff or other patrons, casual destruction of private property and (had I turned the sound up) I’m guessing a very expletive-laden vocabulary.
In my college days I did the two a.m. Denny’s breakfast quite a few times. But I was young and stupid then and the world seemed to be something of a better place.
The amazing thing is the frequency of such things. Denny’s at 2AM means fight.
