The owner of the Cantina doesn’t like droids, so my head canon is that he’s repurposed scavenged droid heads as drink dispensers. Kind of a “drinking from the skull of your enemy” type thing.
This would have been my logic anyway. It’s a rat hole bar in the middle of nowhere. Gotta reuse where you can and if you’re going for cool aesthetic, droid head drink dispensers are pretty metal (pun intended)
