It is 8 in the morning and for 60-year-old mason Amir Khan, a migrant from Uttar Pradesh's drought-hit Bundelkhand region, it looks like the day will involve yet another futile wait for work on a South Delhi road - the third such day in succession. Mr Khan is one among thousands from Bundelkhand who work as daily wagers in bigger cities each year, sending back money to help their families survive successive years of drought. The last three days have been very bad for Mr Khan and others like him - a shortage of new notes after the government banned older 500 and 1000 rupee ones has meant no work.
