Sorry, didn't elaborate much on that and was tossing out common situations. Someone simply leaving isn't a bad thing, time is precious, and people may feel it's a waste of time. From my experiences, a good number of people who quit after one attempt on a fight have been spouting off at the mouth during the fight, and then leave the group with another zinger for good measure. Not all, of course, but a very good number. Just my personal experience, others may vary may experience otherwise. So I guess it was this type of person I was referring to ;)
I don't expect anyone to stick around longer than they want to, but you don't have to be a dick to the group before leaving. Simply leaving, or even just a "hey, I'm sorry, but this isn't going to work" before dropping is fine. Granted, there may be some people who complain at that point and unfairly label the person an elitist, but that ties into the expectations issue that can be found in some people and shouldn't be condoned either.
