Years ago I worked for a small PC shop and we did printer work too and I ended up with all the printer jobs. I went onsite to a couple places and was surprised at the lack of consistancy in tools. One place was in a prison for the library computer and after emptying my pockets was told I couldn't bring that in so as I reached for my pocket knife to take it back to the van the guard said no, the cell phone can't go in, the knife can.
Another time the guards were not wanting me to take in my leatherman and I asked them if they were going to provide tools then and a lady guard came over to see what was going on and was like "ohh thats a leatherman, it can go"
