These days you are lucky you can get someone to show up for anything.
Different trade (IT work) , but right now for people not on one of my perf plans (there are about 5 people) I basically charge $100-200 to show up. USUALLY however, if I just have to go , find out I dont have the shit we need, and stay 20 minutes or less and then come back some other day for a fix, they're usually not going to get hit twice just on the basic, but the ticket is probably going to be north of that basic anyways.
