Please do not help people with notebooks, tell them you are n00b and know nothing about technology.When I was a Spur waiter I hated those bottomless coffee people .
Having them sit at my tables and then still have to help them with their laptops will make me kill.
Don't doubt the technology. Been there, done that.One has been running for a year and has never fallen over. The others all happened this year. You get 50MB in total 20 up 30 down at quiet shops and 30 total 10 up 20 down at busier shops, its free and it only allows one session per day per pc.
