Now coming to the fair practices.
I find many of the on line service provider companies providing services of airline or railway ticket booking, travel booking, hotel booking, show booking, etc are doing fairly good service. Most often they automatically restore the moneys transferred where bookings were not effected. They also attend to the complaints to restore the customer confidence. More often their business models are hassle free in general. The general complaints are on account of the Internet connection failures or power failures which are mostly beyond their control. But their softwares do take care of such eventualities. Most of these companies also talk to their customers or send them e-mail communications to the satisfaction of the customers.
I also find the so-called radio taxi services which have been started in some of the metros reasonably good. These business models if extended on a large scale covering more areas would immensely help the general public. The main hindrance in the expansion of such businesses are the local administration and the state governments.
On the overall, there is immense potential in India for companies who wish to do business in a fair manner.
