Meh, if you have the opportunity to choose who you drink with I'd beg to differ. I've had many an enlightening discussion around how to deal with management, or some new angle to tackle a problem, or bringing to light a previously unknown opportunity, or a meta-discussion around how to deal with life itself and not just the job. I've also made some great friends along the way.

Now forced events with peers of varying closeness I'd be more likely to agree with you.
