As you observed, a shrewd tradesperson never refuses work, they just give a terrible quote. I had an aunt where the neighbour's son replaced a section of fence and just said to pay what they felt was reasonable and it was difficult for my aunt to come up with a number. Probably wasted a few hours coming up with that number, ugh.
