Fred-

People that save chairs hours before sitting in them are afflicted with "Only Person On The Planet Syndrome." They are the same people that leave their shopping cart unattended in the middle of the grocery aisle with no way to get around it while they are struggling to find the chicken noodle soup. You may have also heard one of them talking really loudly on their cell phone while they were standing in line behind you at the check out. It is not you that they are concerned with because only they matter.

Funny story, I was once falsely accused of the chair saving transgression while on a cruise. A jury of my peers acquitted me on the spot (mostly because I never left my chair) but my accuser asked my wife (who he did not know) if she would let him know when I died because he wanted to pee on my grave. Needless to say, no more cruises for me. I go to Negril now. I just hope that I don't run into these people that are attacking you because they don't think that you are as chill as they are.
