Tsukumi Dolphin Island, a Sea World-type park in Japan, employs an otter named Kotsumekawauso to fetch patrons juice from a vending machine. You have to pay for the juice, but the adorable squeaking is a free service.

Obviously animals have their own dignity and should not merely be employed to carry our juice for us, but on the other hand, I’m not sure juice that hasn’t been touched by an otter is ever going to taste good again.
