It has always been a waste of time for me. Most people abuse it with "how do I" calls, not to mention when they are told what it is going to cost, their emergency isn't quite so bad. By far, the worst abusers are people doing an office move over the weekend. They find one little thing not working properly and they are on the phone at 10:00 on a Saturday night. They pull the "we are paying movers" game trying to shame us into coming out. It's just not worth it.
I get at least one emergency call every weekend and it's always a waste of my time to even talk to them.
