I have done a few and generally they are fine and fairly quick to do. There are some confusing questions, but once you have a few under your belt, the go really fast.
I always use the scenario, my wife has me on a honey do assignment we are moving into town in about 2 weeks. I need some help, services offered, internet, tv, phone and X1.... I don't have the address, she has been taking care of that, but its on x street.....
Playing the dumb husband works really well and you would not believe how much they bend over backwards to help.....
Yes they can bonus really well at the end of the month.....
