Just a quick idea concerning those additional small tokens (instead of throwing them away):
How about making it possible (for $$$$$$$$$) for a regional manager to buy up beverage vendors (covering them with the small tiles). They would then deliver exclusively to their company and the company could choose what kind of beverage they produce (1 type of beverage per turn)... ;)
We considered such a mechanism during playtest but it can turn *very* nasty... However, if the price is right, maybe a good idea.
