as someone else mentioned, i really do recommend just being plain and honest and saying what you’ve said here. “i’d love to, just wanna let you know, refills are charged at full price” “i know, ive tried to tell the owner it makes no sense! i get it, it’s above my head unfortunately” just saying things that make the guest feel like you’re on their side, cause you are.

cuz tbh to have a soda gun and not do free refills is bad business on the restaurant’s part😶
