in that situation i'd order my food, and choose to eat someplace quieter. I dont eat on the highway either. too loud.
if anyone impeded my space, i'd instruct my friend to hold the cell for video while i let the guy slug me, then i'd beat him to a pulp and post it to the web before the police arrived. And if the idiot pulled a weapon, i'd execute him in self defense, and post that mfcker too.
33, my guess is that youre so pissed off at a group of people because you dont enter it. Like, when i see a crowd of pricks, i'm wearing a fanny and looking 195 pounds with small bones, i don't get fucked with. youre bigger than me - I can't imagine anyone bumps you?
so why let anyone bother you? I order my food and get it. I handle my business and move on. I haven't been 'fucked with' by anyone in a decade, to be honest. I don't look like prey, and I dont think you do either? So just face the people you dislike - and the resentment might go away. you might strike up a conversation about how many wu tang members are still around, or when the new jay-Z track is dropping.
