bartender keeps day job

bartender: twist of lime for you?
crystal bee: do you have any……shoes?
bartender: *gets creative*
crystal bee: thanks. *steps into crusty lime twists making twig snapping in woods sound* *foot bleeds*
bartender: oh god. would you like me to make you another one?
crystal bee: no it’s fine. *shoe squeezes lime juice into wound*
