I will say it was nice experience.OLA cabs are easy to get, cheap to your pocket and undoubtedly you have coupons to use. I made a ride from Arrival 1C to gurgaon and it just costed me 100 Rs(As I used coupon).
Drivers also talks in a nice/respectful manner as they are more concerned about the feedback at the end of ride.
If you are lacking with cash or don’t have change, you have an option "OLA MONEY". Dump some money in it and it will be automatically debited.
TRY it once!
