It was a red eye flight . And after take off and the first service the flight attendants were no where to be found except in the galley. When I went to the bathroom, the entrance was blocked by a FA sitting and he basically exhaled loudly as he had to move his legs so I could get in. Never mind I was a comfort plus passenger and traveled to the back of the plane to go to the bathroom. I know I can go up to first class because there are no rules to prohibit me but it followed the “air” rules and was the flight attendants were rude as if I was putting them out. I will always fly delta but get your crew in check. I’m a former flight attendant and the crew is not priviledged. They are hired and paid to do a service.
