Big trolleys not allowed on omni buses

For international travelers, if you are commuting on omnibuses, Maximum allowed weight is 20kg per passenger. If you travel with large trolley(158cm), omni buses asks you to pay more. And try to trip you into believing its not allowed and so and so. Paying is fine, and travelers are ready to do so but, the chatter up leading to it is not pleasant and would disturb your peace of mind. At the end of the day, it is still privatised public transport. So prefer your own car for to and fro, hire a driver for your car and travel to the airport city if you guys are travelling internationally and need a drop off to airport.
