k well i dont build/repair pcs for a living, but 2 years ago.. my friend was working at some pc store and his co-worker was on vacation so he was alone. Since it was a weekend, and i had nothing better to do, i dedcided to go help him out. People were dropping their pcs at the shop for hd replacements and other little things. I got to work by replacing the hard drives and as i was doing that, i felt kinda thirsty. I grabbed a drink from the mini fridge and as i was drinking, i left my drink on the shelf. The tools were all over the shelf so i grabbed a screw driver without looking and accidentally knocked the drink over. Because the shelf was just right above the working table and the pc, the drink spilled all over the tower.
Luckily my friend was out at the counter talking to customers while i was at the back. I began to panic and didn't know what to do. So i quickly cleaned the mess up and replaced all the hardware inside the tower with used ones. I know it was wrong but i wasn't allowed to open any of the new parts and the used parts were gonna be sent back to the manufacturer.
Luckily, the guy who owns the tower knew absolutely nothing about pcs or whatsoever. Essentially, he hadn't noticed that the hardware was replaced with used ones.
Ever since then, i've never drank at the working table.
