Long Time No See.... what are those things?

So I have been gone for a while, mostly because I hate the job. lol. So I had my first job today out in the woods. I drive almost two hours to get there. A satellite Internet job. I arrive and it's out in the middle of the woods. I knock and he's not home, of course. I go and wait in the van, and he pulls up. First things first, lets see where your computer is at. We walk in, we get to the dining room, no computer. THEN he says do we need electricity? WHAT?!?!?! No lets just start rubbing our feet on the carpet and power it up with static electricity!!! Wait, where's your computer? No computer? What the hell am I supposed to hook up the modem to?!?! What a complete moron! Bend over and I'll hook it up to your ass, maybe you'll get high speed... Oh, and get this, he says he didn't "know" he'd need electricity or a computer to hook up to! Next thing I'll be getting the whole, "OH, I need a house for you to hook up my satellite system?" So I call to reschedule his appointment, when I see him rubbing at his translucent 80 year old legs, how odd. He kept wiping something away... So call made, he apologizes for wasting my time to which I say it wasn't a waste at all! IT SO WAS! I get to my van, and I look down and my legs are covered in these black specs... what is this? I too start to wipe at my pant legs, damn things are stubborn. What was it? Any guesses? There had to be at least a few hundred specs on my pants.... I pick one up and take a closer look... this spec has tiny legs.... then jumps from my fingers...FLEAS!!! WHAT THE HELL!!!! I start wiping like my legs were on fire. I spent the next few hours picking them off my legs, my socks, my shirt.... DISGUSTING! That bastard had better get his flea infestation under control, cuz I sure as shit ain't doin that job covered in fleas!
