Not at all. I've watched them for years all over California and in a few other States. I used to film them and show friends, back when making movies with a pocket-size device was novel. They tend to loiter and run the machinery excessively whether it's needed or not. I'm not sure why. A display of 'work theater' to impress their clients? Or maybe it's to keep the driving/onsite ratio reasonable? Like, they have enough clients to make a living and don't feel like doing the extra travel/setup/teardown to add more, but don't want to just go home for the rest of the day when people are supposed to be working, so... run the leaf blower? I rarely see them in a hurry. It's almost like a form of meditation for them.
