A town that fills with the temple's calendar
Mannargudi's commercial year runs on two clocks. One is the temple's: the Rajagopalaswamy temple, a Vaishnavite shrine Hindus call Dakshina Dwaraka, holds festivals through the year, with Panguni in March and April, the float festival in Aani and Adipooram in Aadi. On those days lodges, messes, cab drivers and flower and puja shops hear from strangers as well as regulars.
The other clock is the delta's. Paddy, cotton, sugarcane and pulses grow around the town, and rice traders and transporters work to the harvest. Their customers are not strangers: they are millers and farmers who have dealt with the same counter for years and expect to be told when a load is on its way.
Both clocks reward the same habit on WhatsApp. Let the customer write first, answer from a shared number, and keep the few messages that must go out unasked, the booking note, the loading note, the payment reminder, as approved templates.
