I'm sure the butcher was really nice :D I took a picture of a butcher in Hong Kong, too. But I didn't ask beforehand. I just shoot ! Anyway, he looks very serious and a little bit scary on that photo ! But he saw me photographing him and he gave me a huge smile !
I like #1 best for the subdued tones and nice pattern.
#4 would make a nice pic especially with the woman's feet resting so comfortably feet on the chair :). I sense you are trying to get a closer and better angled shot but hesitated :).
As often, you are right ! But I couldn't move without making obvious that I was taking a picture of them... so I just stayed where I was !
