This document discusses opportunities to improve the customer experience at stores. It notes that crowded aisles with too many items and variable customer traffic at checkout counters can be issues. It suggests using technology like RFID to only stock shelves as needed, limiting items, and using sensors to optimize the number of open checkout lanes. It also notes that some customers know what they want while others browse, and a solution is to allow ordering exact items that can be filled at checkout like a take-out order.
