Character/Comic Idea: "Tales from the Express Lane"

Just an idea for some comics I might do based on the B.S. I experience at my job as a cashier with stupid customers and co-workers doin' stupid stuff. I'm thinking the title will be "Tales from the Express Lane." The comic itself would be from the perspective of the signs for the registers, the main character being the express line simply named "Express". Co-stars would include the Self-Checkout, Express's crush Register 4, male-supermodel Register 5, the store manager, several cashiers, and of course STUPID CUSTOMERS! ^__^
