We were flying from hou to new orleans Thursday June 30th and encountered a weird flight attendant in first class. He was mean and rude. The wife and I never made any coment to him yet he comes over and slams my seat back up to the upright take off position and scolds me for endangering the people behind me. I had the seat upright! It may have been down one click. He then barks at my wife for her purse strap sticking out from under the seat. Oh, the flight was an hour late for takeoff. We the customers ought to have been in the bad mood. He slams our drinks down and then ******'s them up before we finished. I ask him in a nice voice why we had the delay, had the plane had engine problems. He shouts at me that there was NO PLANE. The plane was late. I notice he has no name badge on so I politely ask him his name, his eyes glared at me and ask me what my name is. I tell him and he runs to the front and comes back with a passenger list and circles my name. I ask again his name and mumbles Darian or Damien. He is a black male in his 30's. My wife is the first to criticize me when I mess up, but she told me that this guy was scary crazy. She should know, she is a medical professional that has worked with the mentally ill for 30 years. I think he is a grenade with a loose pin. I pretended to sleep the rest of the way to N.O. and he sent a female out to serve us the rest of the way. This guy is a huge problem. If he tries this crap with the wrong guy there is going to be fireworks. I bet he has already been in conflict with passengers.
