I hope that Google finds a smart workaround for the need to login on a web-browser - it is an annoyance every time I walk by a Starbucks.
There are a lot of subtle ways of regulating how long customers stay. In recent years, I've seen Starbucks replace cushy chairs with stools and rigid chairs that most people wouldn't want to spend more than 20 minutes in. I've seen more than a few restaurants block off wall sockets. And music can be effective at dissuading loiterers without them being too aware of it - even innocuous coffeehouse stuff can be fatiguing after so long.
