Which customers to be given priority to service better during peak seasons : (a) loyal existing customers (b) Large prospective customers ?

Loyal Customers... earning customer Loyalty is hard and expense job which can't be compromise d...

large prospective customers may never come again but loyal customer will definitely come again if served well....

Loyal Existing Customer because if we loose existing customer we cannot make again good business relationship. Large Prospective customers like oil and gas industries we can get enquiries anytime online enquiries to close the order. 

Marketting is more about managing profitable customer relationship.In my view It depends on the product the customers are buying If they are buying the same product then I will go with Large prospective customer since marketting is more about attracting more new customers in the same way I will not put down my existing customer I will make other possible ways to meet his requirment.

Without neglecting Loyal customers, priority to be given to any customer who is prospective of gaining or regaining one whether they are large or lost

LOYAL CUSTOMER KNOW HOW WE ARE SO THATS WHY WE CALL LOYAL CUSTOMERS AND THE LARGE PRESPECTIVE CUSTOMER IS A FUTURE LOYAL CUSTOMER, SO MY POINT IS ASK SOME SPARE TIME TO LOYAL CUSTOMER AND SPEND SOME TIME WITH LARGE PRESPECTIVE CUSTOMER
