Some gripes / complaints about human behaviour :
a. Gentleman who open the door to the Men's Room wide open in an office building where the Men's Room and Ladies' Room are opposite each other beside a busy corridor
and "men at work" are quite visible through the door.
Can't these gentlemen be considerate and open the door only the slightest and close it quickly behind them ?
b. People who sit in the middle of the bench -- eg at a Bus Stop or at a Park -- leaving inadequate space for others.
c. People who "hog" the doors in lifts and trains even when they are not getting off at the stop where the largest number of commuters will be exiting the lift or train.
