I really understand your dilemma.
I have used the same upholsterer for 12 years, but not needed his services in the last year.
The other day I went to see him and walked straight past him outside his works.
He called to me and I turned around and all I could see was his hair.
I suppose he was thinning before but I never really noticed.
Now he has this 'thatch' of hair plonked on his head.
Its not a bad hair piece, its just not right for him.
The colour is slightly off, the hairline too low and the cut doesn't suit him.

I have to go back next week to pick up my stuff and I keep thinking how can I say something and not offend him.
All I want to do is help, he's a really nice guy in his 40s and a few adjustments and it would be ok.
But Devildan is right. I can't say anything.
By the time I'm due to see him, I'll be needing to do a re-attachment.
I did wonder about showing him mine and then asking him about his...... but I still think the answer is NO, I shouldn't say anything.
