What is the purpose of the dome on this vending machine?

Here is a snack vending machine
that has a solid dome
on the top of the housing. I don't recall having seen such a thing on other vending machines, but perhaps this is due to other vending machines being taller than I am.
I assume it has a functional purpose, as it would surely be cheaper to design and build a unitary housing. I believe I see what might be a foam gasket between the dome and the housing top. This leads me to wonder if it might be an air filter or vent.
I've searched Google images and Flickr for photographs of vending machines and/or domes, but most photographs only show the front. I searched online vending machine parts catalogs for "dome" and "vent" but nothing came up.
Could it be an antennae housing?
For what it's worth, the machine is located in Seattle.
