Yeah, I can't recall anyone ever putting it down explicitly as a line item, but a number of them will tell on the phone you there's a minimum charge for coming out. For some reason locksmiths seem to always do this.
I expect a lot of jobs that locksmiths do are pretty quick and easy for them. I went down a file cabinet lockpicking hole a couple of months back and ended up just drilling out the lock. I expect a locksmith could have handled it in a few minutes (if that) but if they had to drive 30 minutes to my house they have to collect for that somehow.
