"My" electrician says "sorry mate, I'm driving. Can you send me a text or call around x pm and I'll let you know". Seems sensible to me.

So politely explain the situation and move on. It works the other way in that if the tradesman sees you as flexible they start taking the piss when rationally they should favour the flexible customer.
It's the failure to communicate which is most frustrating and I don't understand it. If the tradesman says "I hope to make it Tuesday but this job may overrun so can't promise , and then calls me to postpone" is that, over time, going to lose him business compared to saying "I'll be there on Tuesday" and then mysteriously not appearing?
