A regular patron of a popular coffee chain was in for a surprise when he ordered his regular cuppa at an outlet near Paytm headquarters in Noida. When the steaming, frothing cup arrived at his table, instead of the usual heart or smiley face on the foam, on it was written: Paytm. The server said that was a new way to remind customers that they could pay for their coffee with the e-payments wallet. “Is this paid for?” the patron asked. “Of course,” replied the server. “Why else would we do it?” Now that’s one steaming, hot advertisement.
