Things to do at the airport

It's 2.30am and I'm in London Gatwick Airport right now.

Ways to kill time at the airport:

1) People watch 

2) Window Shop 

3) Surf the net

I was excited about going back to Glasgow, but my enthusiasm lasted for just 4.5 hours. I'm feeling so sleepy and there's another 4.5 more hours to go. Maybe I should join the snooze party too.
