You just contradicted your own argument, you say he doesn't owe anything to any of us, yet we are entitled to the service we agreed to. Well, very few of us have received the service we agreed to and are waiting longer than we were told both before and after Mike's family troubles.
You cannot say that we should all sit tight and not question why our watches have not been returned (repaired or not) when you have no clue about the in's an out's of each our individual 'service agreements' with Mike. Let me hazard a guess and say you don't have any watches with Mike?
The thing that annoys me, coming from someone who runs a small business, is Mike's lack of customer service, its all very well for you to say he's a craftsman and his expertise takes time, I don't think anyone would disagree with you on that, however, a professional would have contacted his clients, apologised for the delay and given an ETA on when the job would be finished. This hasn't happened.
I have been patient, I PM'd Mike once, no reply. Sent an email 5 weeks ago, no reply. Sent a second email on Tuesday this week, still no reply. If you find that acceptable from a business, any business, then more fool you.
