Fast food?

Couple of stories on sort of the same theme - one from over there, the other from over here.  US first - a branch of McDonalds in Queens, New York has taken exception to a group of pensioners who have taken to spending most of the day in their establishment - spinning out their coffees and bags of fries and such.  The police have been called to move them on, but apparently they just walk round the block and then go back in and start again.  So what about over here?  A coffee shop has opened in Shoreditch London where the drinks are free, but you are charged for the time you spend there at 3p a minute. So obviously not the place to go for a leisurely drink and a chat.
