I'm never going to shake hands with anyone here at work, ever again! Every time I go into the bathroom, I see someone from my company use the toilet, flush and walk out the door... Everyone! From the CEO, down... no one washes their hands after fiddling with their junk - and it grosses me out to no end.
Actually, it isn't everyone. The geeks - the programmers and development and QA people I trust. But people from marketing, sales, etc. just stay away from me, please!
