Yea, I used to have to work with a guy like that.
When I was researching which laptop I wanted for Christmas (I wanted a decent gaming laptop so I could go anywhere and still play my faves) he decided to drop his two cents in, but decided I should be putting that money towards a desktop so I could get THAT MUCH MORE PC. I then had to remind him I'm not carting a 35 pound case plus monitor everywhere I go and I wanted a laptop.
This went on for weeks. And it's not the first time he's done it. And he's a born again Christian, so he's worse on that now. *sighs*
But I'm on 2nd shift now and pretty much won't have to deal with him at all anymore. There is a bright side to having your workplace reshuffle your life sometimes.
