What do you do to kill some time at the airport?

I like to collect some things to do without lounge-access. Where you'll get the best food, internet-access..... What's the best place to see some people and their funny habits?

Let's start in Germany:

TXL:- in summertime spending some time at the Restaurant "Take - off" terrace with a cold "hefeweizen"-beer, watching the planes..... (main hall, 3rd level, beer with great view for just 4€)
- wintertime: sorry, one of the most boring airports worldwide

FRA: visit the "beate uhse" adult-store , take a look at their products and their customers (terminal 1 A+B, 2nd level)
