That was more of a slow roll that a "show your hand" situation. In most cash games, if a player is all in, you are not required to show your hand right away, even though it is proper consideration to do so. You could have asked, but that is more of a "house rule". He was more of an a$$ to slow roll you.
Hold on to the KARMA factor. THat'll bite him eventually, and if you see him often, maybe it'll be you.
