Why are the glass tumblers and the coffee cups in the left cabinet stored right side up:
But the wine glasses and the plastic tumblers in the right cabinet stored upside down?
The nearest I can figure is that I loaded the right cabinet initially with the wine glasses, and a youth spent in taverns made me put them upside down, and I put the other glasses that way to match and didn’t think of it when I loaded the other.
It’s always been that way, though, and likely always will.
