We've been going to WDW for decades. Here & there, we run into a cast member who is less than pleasant. My approach has always been to assume that they probably were just on the receiving end of some guests unwarranted verbal assault (something we see very often at WDW) and we try to be extra nice to level out their bad karma 
I NEVER am so self important as to expect perfection when it comes to customer service at WDW. Those folks have a tough row to hoe and guests get ruder all the time. Frankly, I'm amazed that they manage to maintain as well as they do in light of what they are forced to deal with every hour! I can't fault them for losing their veneer now & then.
