AS 1933 12NOV LAX-SFO (A321)
I mentioned to the FA that I was excited they'd added sparkling wine (along with water/juice) for flights departing after 10am and he said I was absolutely wrong, that the policy had changed again and this had been confirmed to him by his Supervisor the day before. He was clearly having a bad day as he also then rudely added that it was due to the F cabin being filled only by upgraders (I was on a P fare) before he stomped off. Everyone in Row 2 just raised their eyebrows and chuckled at him.
He was very curt for the rest of the flight and I've already given customer care feedback.
