My fave is when other passengers on planes call family/friends to say their plane has landed at the airport and they will see them in five minutes inside the terminal. I want to grab them by the throat and say through clenched teeth...can you not wait 5 FREAKING MINUTES????

 

I once sat next to a man on a northbound long-distance Amtrak train who had a 45 minute cell phone conversation with a friend, describing in detail each Amtrak station through the DC corridor. Prayer alone kept me from throttling the SOB who (thank you God) finally got off and met his friend at the station in Maryland.

 

The other one is when people leave their televisions on when they have visitors. Or leave their televisions on all day, whether or not they are watching it, whether or not they are even in the same room.
