Travel experts report that public transport services are not meant to provide comfort to travellers. And that if passengers want comfort, they can do so by digging deeper in their pockets to travel in special and spacious compartments (business or first class).
This means that if you are travelling as an ordinary traveller, there is no exclusivity and your comfort out of the normal is limited. One of the causes of intimidation, quarrels, and conflict while travelling as an ordinary passenger is room comfort.
