jerk off people? rhothgar and frug?

[highline]

Let me ask you all something....so Rothgar and Frug asked me to help them kill the commander in blackburrow to which I replied I had to log off b/c my son just woke up. He said if you come and buff us I'll pay. So I spent another 10 minutes giving them shaman buffs and healing them to full, afterward frug went ld and rhothgar just ran off and laughed. Is this common?
