Uber cabs are a boon to common man who wants to travel in 4 wheeler, though not owing a personal vehicle.
By applying "HAPPY200", one can avail a discount of Rs.200 on h i/her 1 ride.
There many other free ride and discount ride coupons that are being updated day to day.
No matter where ever you are, a few minutes away is the Uber cab. Even though, there is an option for pre-booking, I personally suggest to book instantly in order to avail better services.
Of course, in some sign-up cases there are payment mode problems. But yes, they are being sorted out.
And few cab drivers are little rude and do not follow the ethics but, Uber asks for customer feedback on every ride through which one can rate and comment on their particular ride.
Overall, I say uber cab services are doing very well in the market.
