Buses and car parks

• Are unusual places for having sex, but quite appropriate for making money.
• Not with sex. But with wending machines.
• I feel that many of us would be willing to buy that cold drink during a hot&sweaty traffic jam...or at least some chewing gum to offer to your co-passenger and ease his breath. As for parking lots, that would be continent.

1. Find suitable (small, but rigid) machines online. Or find someone who could produce them.
2. Make a business plan.
3. Go to public transportation office and car park owners and offer them your solution. Its a win win win, because they improve their services, their customers get better choice and you get a cut.
