Holy cow imagine having this guy working on you.  he'd probably poke you in the eyes if you upset him.

My word, what a nut!!

He needs ALOT of therapy. I bought a used TV (he promised a 90 day warranty) from a guy(TV repair shop) like that once. It broke and we went back to get it fixed. After taking it back about three times and asking for my money back, he threatened to "kick my ***" and followed my truck on foot threatening me and beating on my truck. Unfortunately the world's full of them.
