Whoa...crazy. Care to elaborate? Obviously you don't need to give too many details but I honestly don't even know how a drumtech could be in a position to be cool or a jerk to fans.
I think what Snob said sums it up fairly accurately - whenever the fans would try to engage him in conversation, he would always blow them off. This happened to me several times, even if I happen to be at a soundcheck or something else where it was evident that I had a connection to the band. Didn't matter. Now if MP had introduced him to me, perhaps the situation might have been different, but he's always struck me as a jerk, and hearing that other fans have had the same experience is all the verification I need of my opinion of him. Eric OTOH was always kind - maybe didn't always have time to chat, but was pleasant and never gave you the impression that he thought you were scum like Jose did.
Interestingly enough, in chatting with another crew member I've gotten to know over the years, he told me a couple stories about Jose, such as one where his psycho wife was at several shows (maybe even on the road with the band) and was causing all sorts of problems that Jose was told either to send her home or else he himself would get fired. (He sent her home). Granted, that's not him personally, but I still found it to be an interesting story that fills in a few blanks about who he is.
