It is also our responsibility to educate people to proper etiquette- maybe the OP could have asked the group if he could play through quickly. It takes a real douche to say no.
More frequent than the group who flat-out says no to a play-through request is the group who takes their time, throws multiple shots, and then hustles to get off the tee before the person behind them gets there.
