A self-service format lowers labour expenses and removes complex transactions. For your Mini Supermarket Investment, this translates into larger margins and better customer satisfaction. Everyone feels good with tidy aisles, signage, and barcode billing - the operation time will certainly feel organised even if it is small. Shoppers enjoy the ability to wander - especially in Tier-1 and Tier-2 cities where urban shoppers value their time. You can have hybrid billing - counters with staff for elders and POS counters for everyone else.
