Yes customers over-staying, complaining, not spending enough seems to be the problem Cafe owners have. One near me had a threatening sign that "if you're sitting, you need to be sipping" (you're welcome, but not for long). The solution of a printed-flyer to tell specific customers to move on seems like the good idea here, and I would think a cafe owner could print a card which says "we need to pay the bills, you've taken this table for an hour, please come get another drink." or maybe ask two laptop users to share one table. Also noteworthy is the Capital One (ING Direct (USA)) model where laptop users are welcome, but the Capital One Cafes are brand enforcing, not profit making coffee shops.
