You help one neighbour with their car and it snowballs.

I do a lotta neighborhood non-puter stuff, cash no receipts.
I still maintain a lotta classics from my business, old, good customers.
Biggest mistake my wife and I found, was when anchored in a quiet bay with a buncha other boats, . . don't even whisper the word "mechanic" for any reason/discussion.
If you do, there will be an immediate splash of dingys dropping in the water, and thrashing of oars/outboards from hoards of folks eager to have a repair done 100 miles from nowhere, lol
shhhhhh . .
