"Share in you twitter that you are here in TGI, and you can use the internet for free." This will be a phrase inside the restaurant, and there will be a special space to the computers or notebooks, and when people want to do something in internet, they will not need to go home. Just a little time there in the computer and will be back to be with friends at friday's. There will be a limit of time for every person that tweet something. this will be calculated depending on the restaurant. 30 minutes maybe can be suficient.
