That's why I bought a phone that can play video games--for those moments where one inevitably just to sit and wait.
On a similar note -- the G'ville airport operates on a clock that is 5-10 minutes behind SCT (Standard Cellphone Time). Often I'm headed to the airport seeing that I'm really hitting the bag check deadline according to SCT and when I walk in the door find that it is much earlier than I thought. One would think that these various systems (cell towers, airlines, etc.) would be better synchronized given today's technology.
