Not so much an am I being unreasonable, more unrealistic.
Partner is a self-employed window cleaner who mostly does regular window cleans for his customers. He does occasional one off jobs but 90% are regular diarised jobs
Recently his van broke down and he's been using the family car/hiring a van depending on what's going on each day, to still be able to work. Whilst I respect his work ethic, juggling this and trying to get his van diagnosed/repaired is clearly stressing him out. I've not had any regular service before but in my opinion his customers wouldn't mind missing a clean for a week or so while he gets it all sorted. However he's firmly of the belief that he can't let any of them down and needs to continue as he is due to everyone being on a certain schedule.
Am I being unrealistic to think that the customers he's been going to reliably for 2 years wouldn't mind missing a clean or waiting an extra week or so? Would it make people look elsewhere for a window cleaner?
