I have magnetic signs on my truck which I pull off and toss in the front seat every night to keep the HOA neighborhood patrol off my case. NO "work vehicles" can be visible at a home after 8pm. unless its an emergency repair.
As everyone else has mentioned I get several calls a year from someone you might mention they were beside me on the road or behind me at the drive-thru at the Whataburger and give me a call or to ask about something at their own home.
Having those signs can sometime be a hassle too. You have to be really courteous on the road or someone will call the number on your sign to complain about something. When I've gotten those type calls, I always thank them for letting me know and that I'm going to fire that guy when he comes in.
