To be fair, Gillian’s the only one that abides that rule nowadays. At some point in training all instructors flat out say “There’s nothing in our contracts that actually forces us to make lame jokes when serving drinks. It’d be troublesome for mute or non-english speaking bartenders”.
However, Gillian didn’t get formal training so much as he read a manual Dana had handy, so he’s unaware of this (And Jill finds it too funny to go out and clarify it).
