talking of coffe, when my mate was working the it call centre helpdesk at some compnay few years ago, some woman called him to say that she'd spilt a cup of coffee on her keyboard and what was she supposed to do about it

he said that all she needed to do was to unplug the keyboard and wash it out under a cold tap and then leave it to dry out and if this didn't fix it he'd send out a new keyboard

a few hours later, he was called into his boss's office to ask why he'd told some posh woman to wash her laptop unde the kitchen sink
