I regularly play a live game in a B & M casino, usually about 4 or 5 people at the table are "the regulars", not pros per se, just the same people who play the same game on the weekends and tend to all sit at the same table.
Over the past year, I would say that the core group of maybe 8-10 people (usually not all there at the same time) have become friends, and do other things together at the casino in addition to play poker (eat, table games, hang at bar, etc).
When we are at the table there is little if no slow playing. If I can felt them I go for it and they do the same. About the only difference in play between us and someone "new" to the game, is we may tend to have better reads on each other and often there are some unbelievable "hero calls" (which often results in the aforementioned felting" or "monster lay downs".
Personally I find it enjoyable to sit with people you know and can have conversation and good table banter with...its a good skill to be able to be friendly at a table and still be able to observe the table and take in all the information possible....
I would add, that if someone feels that they can not play their "A" game while either being friendly or making friends at the table, then that person should try to avoid becoming friends with people at the table.
BottomLine - I agree with what shift work said:
