One time I got a service call to go out to a house and fix a computer that continued to lock up. When I arrived at the "house" ( a trailer that was up on blocks) "Jethro" met me at the door. He was about 6'1", and 130 lbs, White tanktop teeshirt and stripped boxers. I walked into the house to find his wife, (5'1" and about 300+ lbs) and his half wit inbred son sitting infront of the TV watching a tractor pull. Well there was enough smoke in the house to send most healthy people to the hospital for smoke inhalation. The computer was in the back room, covered in dirty smelly clothes, I "exhumed" the unit, and took it out to my truck where I could breathe. I cracked the case, only to find thick, tar and nicotine laden dust covering everything. I begin cleaning by removing each compenent and laying in on the back of the truck and pouring alcohol into a tray and letting it soak. Now here is the good part: I remove the Celeron processor only to find a decapitated palmetto bug stuck in the heatsink and fan (the head was in the heatsink). About this time, "Jethro come out to ask how llong it will take because his membership at his um, er "private site" will expire, and he needs to download the latest "movie". I take the case to the sink inside, and wash it with soap and water. Once done, all compenents and the case is dried and blown off using about 6 cans of compressed air. I get everyting back together, throw an extra case fan in there, as well as an exhaust fan. I plug all the wires and cables back up to the PC, and begin checking the hard disk, Jethro had about 6 gigs of his 8 gig hdd filled with all kinds or porn. I told him that I could install a 2nd hdd for $200.00 more, ( the hdd only cost me 30.00) and set it up so he could use that to store his "movies". Cash only though. He paid, I set it up and got the HECK OUTTA DODGE!!!. Plus, based on the "movies", I never sat in the chair he had in that room.
Final cost of service call $550.00, total time there 2.5 Hours
