Did you win? Sounds like you probably did if he got so about it. On the other hand, just because one of them throws a hissy fit at the drop of a hat or gets physically threatening doesn't mean they failed to get their way.

I knew and had to spend a lot of time with a former small business owner who lost her ~100 employee business and ended up living the worst nightmare of any capitalist: being a wage worker. Having to exist on the other side of the class divide and get exploited rather than do the exploitation went a long way in humbling her I think, though it happened a decade before I met her. But she still remained one of the most petulant people, totally unable to admit to having any fault or being wrong in any way and was always just so childish for the most asinine reasons. (Though to be fair I've also known life long proles with similar issues).

Small business owners really do put the "petty" in the term petty bourgeoisie.
