Air Conditioning for Retail Stores

Many years back, about 25 to be a little more precise, when air conditioning of retail stores was not very common, Rekha, a sari shop in T Nagar, Chennai and Kala Niketan, another sari shop on Queen's Road in Mumbai air conditioned their old existing stores. Customers were delighted, stayed longer, bought more and the shop owners proudly displayed a large sticker on their entrance door "Air Conditioned for your Comfort". These were the first retail stores to be air conditioned in India, to the best of my knowledge.
