I was flying back from Dulles on a business trip, Gate A1B Concourse A, departure 5:19pm. I actually tried to go to United to lodge my concerns, but you need a "MilesPlus(?)" number to communicated with them. I upgraded to First Class, I wanted more room because I wasn't feeling well, there were two flight attendants; one was Ashley who was very nice and outgoing, she showed so much empathy to the lady a row or two behind me, due to her seat going to someone else. Ashley was not servicing First Class, it was the other woman long dark hair heavyset darker in complexion. I was asleep when they came around to take drink requests, but I was awake when they brought the drinks. She could have said, oh you're awake, did you want anything? But she shoved the drink toward him and hurried away. Later he flagged her down for another drink, honestly it was ridiculous. It would have made all the difference in the world to show a bit of compassion, I wasn't contagious... I don't get to choose who I fly with when I work, but I certainly will not fly United for personal events. I also realize that one person can ruin it for a company... she did! Not worth the $115.00 upgrade!…
