I think a lot of the OP's points are valid, but sometimes stuff happens..ya know. I mean, I went to a concert this past Friday and I was late, but it was cause my gf got caught up late at the vet (it took over an hour for them to even get called back). We were about 15 minutes late to the show, but we certainly tried out best to enter quietly and find our seats without much commotion (we figured out the rows from the back of the theater where there weren't people sitting).
Also, 9 times out of 10 I remember to turn my ringer off when I go see a movie, but sometimes I just forget.
For your other points, I agree. I often see people entering our building with me maybe 5 strides behind them yet instead of holding the door, they just let it slam in my face. I usually say "No no, I got it, thanks!" when I get in the door. Of course, they turn around oblivious to what was going on.
