There's a hierarchy

Hell yeah - you'd smash that bar & hear a industrial condenser turn on to supply you with artic cold water.

I at least understand the water fountains and experienced them a few times here and there but the sink blender waiting to chop your fingers is a total mystery.

Garbage disposal? They have limited utility, but save you from having to transfer food scraps from the sink to the trash or compost.
The built in ice/water dispenser in the refrigerator is the one that mystifies me.
