You may or may not remember, but in the not-so-distant past, the world was in turmoil because of a beautiful little virus called Covid-19. School doors were locked, companies miraculously started trusting their employees to accomplish tasks at home, and introverts actually started feeling comfortable.
One weapon in the war against infecting each other was being more meticulous about the traffic patterns in retail outlets.
In the case of the gas station/convenience store/tobacco emporium I call home, FastStop, and in the case of the particular location that lays claim to my Monday nights and Saturday mornings, the formation of a line of people waiting to get their selections rung up and paid for was narrowed to a particular aisle of the store by erecting a prominent sign to block the wrong path and encourage people to take the correct path.
The presence of a single line instead of separate lines in front of each register proved to be such a good idea, the store decided to keep that arrangement even after Covidmania died down.
However...
The sign that was designed to create that single line was apparently purchased from a magician's warehouse, because it possesses the unexplainable ability to only be visible to employees of the store. A full 90% of customers...excuse me, guests...either stand beside the sign waiting for an open register or walk right past it so they can collide with folks trying to leave the store with a bag full of eggs, motor oil, and CornNuts.
