He got called out to a nearby plumbing emergency while in the draining-pipes-and-thinking-how-to-best-to-tackle-stage at mine. Which is fine- dealing with an emergency obviously takes priority, and he's left everything sealed up here.
Would it be unreasonable of me to ring him to try to estimate when he'll be back to finish the job here? He's been gone 2 hours now and I'm supposed to be taking DD out at 1, which is why I booked an early appointment. I'm aware that he may be up to his knees in water and worse though, so don't want to be a PITA- but I do need my drain unblocking today, and if he can't do it then they need to send somebody else.
