Wherever you go and whatever you do you will encounter snobbery, I suppose it is part of human nature. I think the thing is that you have to learn to distinguish between casual banter and genuine snobbery/ oneupmanship.
In my experience snobbery is usually a sign of insecurity and/or lack of confidence.
The people who are the most snobbish are usually the people who have very little to be snobbish about.
