Zomato said that 72 per cent of cash on delivery orders since the RBI announcement have been in Rs 2,000 notes.

The Reserve Bank of India (RBI) announced last week that Rs 2,000 notes, introduced after the 2016 demonetisation, will be scrapped from circulation. The notes can however be exchanged or deposited from May 23 to September 30 at any bank and the daily limit is 20,000. And as the notes are still legal tender, they can be used to make payments.
One company that has seen an influx of Rs 2,000 notes since the announcement is Zomato. And the food delivery company had the perfect meme, a Breaking Bad reference, to out the news.
