I think that when we get to that level, we can have no more structure in
tagging. The last structured tag should be "vending=food;drinks", and after
that all the other values should be crumpled into one tag. Something like:

food=sandwitches;Mars;Snickers;bubblegum;chocolate;salty snacks;ice
cream;...

and treat it simmilar to note=* tag. If anyone is going to use that data,
it's not going to be anything more than showing all the text raw to the
user.
