like this myself.

      As a CyberCafe operator, how do you deal with a situation where 
someone has only one card and it won't authorize?

Depends on the relative costs. See below.

If customers don't want to use charge cards, they can require
a large cash deposit up-front,

      How large?  How far are you willing to go while you keep losing 
      business?

That depends - how long will you bet able to get an upstream which doesn't
cancel your service for failure to deal with the problem? That, more than
anything, is the opposite pressure cost - if it costs these places less
to allow spam than to prohibit it, because nobody whacks them with an AUP
saying "your efforts are insufficient", well, they're a business - they'll
go with what's cheaper.

                               just like the video rental
stores do if you try to get a membership without a charge card.

      Really?  I've never seen that kind of behaviour here.

All the time, around here.

Summary: as with every other natural resource, 'the commons' are now held
under market rule. If it turns a profit to spoil them, it will end up
happening. The question is how to make it more costly to permit spam than
to deny it.

And on that note, it's the same old tune, and is no longer operational.
