Do tradesmen ever turn up when they say they will?

I am sitting here waiting for a tradesman to turn up to give me a quotation for a house maintenance job. He is now an hour late. Last week another one failed to turn up at all, no contact, no explanation. That was a well-known local firm with a good reputation.

As I was writing the above, today’s chap turned up, an hour late, but very polite( apart from no apology) very thorough and efficient, covering all bases, with an on the spot price, to be followed by an email.
But it is so hard to get hold of people in the first place, then to get them to turn up, to actually quote. Gone are the days when it was possible to get three quotes.
