Answer:
If sari store A have more enhanced and better customer service than sari store B. Customers often wants knowledgeable and available staff, friendly people, good value, convenience and a fast finish meaning quicker cash register. On the bottom line customers often come to your store because of your service. If you give people what they want and the way they want it and fast finish when it comes to pay up. So if store A have better customer service with average sari price and store B have same pricing system as store A but with low amount of satisfied customers, then obviously people will enter in store A more than store B.
However store B can still have chance by upgrading their status with customer service. Special offer like half-price etc. can help to motivate the store.
I hope that helped you
