Calling previous clients will always get you some upgrades and touchups for things that have stopped working that they haven’t bothered to call you about. I have had two clients recently who changed cable TV providers and were using two remotes. They didn’t bother to tell me they had changed. Mention fun stuff like music around the house, Sonos, streaming video with Roku, etc.

Although I agree with you fully that you didn’t sign-up to clean your van, if you were an hourly employee and had a choice between straightening it up and shining it up versus staying home and not getting paid, what would you choose? Some employees would appreciate the chance to stay busy and get paid. They would also understand that the boss was not getting paid at that time, and would realize he was trying to help them out.
