Negative bias because I feel that way. I may be terribly wrong.
When you are facing cash crunch, leisure activities can wait. There are bank related work to take care of. In the long run, people might spend lesser due to less cash (black or otherwise). Not drastically but very gradual over time. Footfall might grow 2% instead of 3/4% and families might spend Rs 4500 instead of Rs 5000.
Curb on black money affects real estate, luxury car purchase,etc and I feel even leisure activities might be affected but to a lower extent.
This is a long term story which should do well but not so good near term prospects. Chennai land is not yet finalised, CFO leaving, Demonetisation, and in addition inherent risks in these type of businesses (rains, change in school/college schedule, Cauvery dispute, floods, accidents, fresh rides not added) are key risks.
