Zomato is offering incentives for deliveries during smog, while Amazon is providing N95 masks and reporting a fourfold rise in air purifier demand amid severe pollution in the north. "Earlier, I used to deliver 30-35 orders a day, but now it's gone up to 45-50," said a delivery partner working at Zepto. At night, deliveries take 5 to 10 minutes longer than usual because of the smog, he added.
