I guess I might have given you something, but is this a case of what is an insult vs a tip? What might you have charged for this job, several hundred $? It's an unusual situation. The guy might have felt that offering you something was opening a can of worms where he's going to say here's $20 and you're going to counter, you owe me $200.
I used to live in a corner house that for whatever reason had it's address on the side street. And on the street I faced, the number I would have had, was actually the number of a house way down the street. Way out of sequence. I guess this made sense to the local PO at some point but I don't know why. On many occasions I got this guy's packages, which I always called him up about or dropped off. But once, his lawn guy fertilized my lawn. Nice, but I wasn't big on fertilizers or pesticides and didn't think it needed it. Another time his oil guy started filling my tank. I was home that day but out in the garage and eventually heard him and managed to stop it after about 100 gal. Again, thanks but, I had a free service contract with one company and wasn't supposed to go buying oil from another one (the driver didn't really seem to care anyway as long as I signed something acknowledging what he had done.) Last time, cable company hooked me up for stuff I didn't pay for, which they figured out about a month later and took away.
The thing about all of those was, it was a weird situation I just didn't expect, and I was half expecting some guy to throw a bill at me and was just happy to have him go away. At that point in my life, I was in no position to be buying anything that wasn't planned and budgeted, especially something I didn't really want done in the first place.
I eventually had to buy a sign with the number and street name from the side street and stick it by the front door so this stuff would stop.
