I expect my beverage + snack purchase at such an establishment to buy me some time to make it my preferred study place. And every hour or two I'll go back and put coins in the meter and buy another drink. There may be some freeloaders and some who have overstayed there welcome and I don't know what the solution to them is but if there's space for me I'd very much like to settle in with my laptop for a caffeine fueled coding binge for a few hours.
