Roadside candy machines: Mainz, Germany

I visited Mainz on Monday (thank you, American holiday!) and came across several roadside candy machines.

Whoa! It's a quadruple decker.

Zipper bracelets: dang, I could've been the coolest 5th grader out there if I had one of these as a kid!

Eep! This one, near the Hauptbahnhof, is really creepy! It looks totally disused yet has some gumballs in the left side. The right side's dispenser is labeled "thank you" yet the left side isn't. I'm not sure what's going on here.
