Been away too long…

I think I’ve been away from the US too long…. When I moved to this new place where I am living alone now, I bought a small refrigerator. Refrigerators should be rather simple but I can’t figure this one out.

What the heck is this door designed to hold? The large tall area on the right is not deep enough for a 1.25L Coke bottle and it seems the little restraining bar at the bottom is too low to keep soft drink bottles in place when the door closes.
And then there’s the vertical compartment on the left, where I have a jar of jam at the bottom. What is that compartment supposed to hold? Notice it’s got a moveable restraining thingy to hold something in. But what? Enlighten me at cdittmeier@gmail.com or +855 12 608 470 for WhatsApp or Telegram! Please!
