Avoid the social tennis scene at the club, unless you are there truly for the social aspect. Don't go in expecting anything other than low level, rec tennis. You have to let people hooking you, being very competitive just roll off you and try to make some social contacts, hang out with your wife or whatever you want to get out of it other than actual tennis.
If you want to see if the club is for you check out the leagues, ladders, inteclub teams. Ask to play some better players at the club.
