My flight today from PBI-EWR was a 737-800 new aircraft #530 with sky ceiling large overheads. I sat in a exit row window, lots of leg room. The aircraft was completely full. Just before departure the FA as is normal practice asks each all 12 of us at the exit row if we meet and agree to all the requirments of an exit row. Everyone seemed to say yes but as we get to the last few of us, one guy could not speak english which disquaifies him and another guy seemed to have had to much to drink and was slow to respond so he was out. They need to being drunk to the list of those who can;t sit at an exit row.
The second beverage sevice had to be cancelled because so many people needed to use the restroom and the isle were very congested. I guess this is common on a PBI flight.
As we are getting ready to land in EWR, we approach the runway and the women behind me who was yapping all during the flight in a loud voice says were coming in too high then says Hit the Breaks, Hit the Breaks. She was have watched the landing seen in Airplane I to many times.

LOL. The once or twice a year flyers tend to be vocal experts about everything, IMHO. I would bet money that was the vocal flyer.

I once watched from FC an elderly couple in boarding group 4 instruct an off-duty FA in full gear how to place/what to move to get her bag in the overhead bins.

Usually they are denied boarding if the person had to much to drink.

There's a difference (or at least in my mind there should be) between "too drunk to get on the plane and fly safely" and "too drunk to be trusted to perform the duties required for the exit row".
