A shop owner has defended the use of signs such as "no refund" as a measure to ensure customers chose products correctly.
Suncourt Wholesalers Limited executive director Champak Lal Bhikha said such signs were necessary for smooth business operations.
"If signs in question is are not displayed then shops will be often busy serving people who are not sure about purchases and in no time come back for a refund or exchange. We have 10 to 15 such cases every day.
"To cope with this kind of customers we have to have some sort of deterrent or a 10 per cent service fee," he said.
Often, customers are doubtful of the products they purchase. Consequently, they return to the shop for a refund or an exchange, which Mr Bhikha said wasted resources.
"Who will pay for time spent on serving the customer when the customer is seeking refund? Each docket has at least three to four pages and the minimum cost is at least $1," he said.
Mr Bhikha added shopkeepers often allowed refunds but if the goods being returned were tampered with or not in its original condition than then they would decide otherwise.
