At no point should it be given as an excuse for complete change in demeanor to just offhandedly reject every person who preforms poorly. Some are genuinely struggling and would benefit the group greatly for the extra help and attention.

Most people who perform poorly are just poor players and they always will be. There is no point in wasting time on them, give them a few chances tell them you are dropping them because they are poor players and move on. The only time you will have a chance to improve someone is if they are new. No point in wasting time.
