Customers that come in with some steel project scribbled on a crusty Wendy's napkin that try to treat me like a dumbass when I ask what the measurement listed under the mustard stain is
Customers that ##### about a 15 dollar peice of steel, "whoa 15 bucks, really? I remember when that was a 5 dollar peice of steel", yeah, so do I ass hole, but Clinton's not in office and Jordache doesn't make acid washed jeans anymore
Oh Wait, Wait, I forgot the best one, when the next door neighbor comes over (doesn't have to drive, can just drag the sticks 40 feet to where he's pouring his slab) to get 5 peices of #4, 20-0 and #####es because we're 30 cents a stick more expensive than Lowe's
