Lack of courtesy and leadership on part of FA's. Had a plane sit in the tarmac for two hours because of storms in the area. No water, no information, nothing. Like they don't know what to do or something. And yes, we know the rules by reading on how to act as nonrev's but you gotta dig to find it and read about it. In the meantime, we get M&E bulletins that they get on our butts over if we don't read them and sign them off in the computer, but never anything about nonreving. How you communicate with your employees has alot to do with the company's success, including nonreving. Some things apply more in some stations than others. Usually everyone boards first, then the nonrevs get cleared. That wasn't the case coming back from Vegas today when they called out the nonrev's before everyone got boarded. So when to listen for your name is never a sure thing.
