I am partaking a local quick, consumable, gustatory establishment whereupon I spied a problematic carte du jour:
[Of the three screens, one is a noticable blue: “♫One of these things is not like the others / One of these things just doesn't belong / Can you tell which thing is not like the others / By the time I finish my song?♫”] [1] [2]
Methinks the local proprietor requires consultation with the originating equipment manufacturer to resolve the current conundrum.
