Probably Stolen: Display case planner
Compare the quantity and total value of each product group before opening. The display influences the type and social class of customers, but the handbook gives no exact selection weights. Never treat the totals as customer probabilities.

Remove contraband from the display case. The mentor’s note warns that displaying it leads to arrest.
On the left side of the Shutter Door, you'll find the Display Case, one of the key features of your Store. Depending on the type of items you place inside, you can attract one client per day looking to buy that type of item. For example, if you put many [Food] items and one low-value [Medical] item, a food-buying client will visit the store the next day. The total value of the items stored will impact the social class of the attracted client. Upgrading your Display Case will allow you to attract more clients. Make sure to stock the Display Case before opening the Store each day. Do not keep Contraband inside the Display Case or you will be arrested.
