"I'm a flight attendant!
First, I wouldn't recommend drinking coffee or hot tea from the plane. It's made with the potable water and those tanks are rarely cleaned out. None of the crew usually drink it. I had a passenger on one of my flights fill his water bottle up using the sink in the lavatory and I stressed to him that it wasn't a good idea but he didn't care lol
Second, we aren't paid till the main cabin door closes so we are ready to leave just as fast as you are. When there are delays, b#tching at the cabin crew isn't going to help anything! We are waiting around just like you and wanting to get back to our families as well.
Third, smoking your e-cig in the lav will set off the detector!
Fourth, bringing a bag of candy or treat to thank the flight crew will most likely get you free drinks or a seat upgrade, I always hook people up lol"
