Reply to Tech staff, a love / hate relationship . . ?

Generally techy's are great for problem solving, and as long as you don't act arrogant and keep out of the red us DJ's and them get along just fine!

But . .

This weekend I played a gig (not going to disclose event / location as its not fair to target someone), arrived 10 mins early and played using CD's. Tested both CDJ's before starting and one CDJ's auto-cue was being proper dodgy (kept turning itself off and decided to skip a few seconds of the start of each song).

I made the techy aware of this issue and asked him to take a look and possible replace the CDJ but he was insistent of no issues and told me to stop whining! With some very sloppy mixes he eventually realised there was an issue 30 mins into the set but didn't find a replacement till after I finished! It was a shambles, and an embarrassment to play! I can completely understand that he is also doing his job, but there was no need to be so arrogant that he was right?

Anyone else had similar love / hate relations with tech-staff?
