Have a set of lockers outside, or a customer accessable cage area, so you can leave orders for established customers for after-hours pickup.. either a sesame lock with the freshly set combo given to the customer, or a customer provided lock, or a masterkeyed lock assigned to the customer. (Best locks would work well for this)

advertising wall for customers.. enough space for a 8.5x11 flyer, and a stack of business cards.. randomized weekly so nobody can complain about favoritism..
