Really loud, obnoxious, inconsiderate people at a restaurant...those are the people that grind my gears. Do I care that you texted Brittany bitching to her for being a slut? The answer is, quite frankly, NO. So shut your pie hole and eat your Nothin' but Noodles and be happy about it. Not everybody in a restaurant should be able to hear your freshmanesque conversation. I remember the days when all I had to worry about was whether or not the new freshman pledge class of Delta Gamma liked their President...at UAB...girl you just keep getting less and less important to me.
So...the root of the story is, if you see me out to eat, keep your voice to a low decibal and if you must have a loud conversation...make it funny and not completely retarded.
