I am travelling to ludhiana from chandigarh today . i often travel to the same route in a volvo every weekend to go to home. Just wanted to bring it at the front that is it allowed for volvo buses to let passengers sit on the stool while the bus is already full. on the top of it they charge full to the customers sitting on the stool. isnt it a complete non sense when all the seats are already occupied what is the point of making them travel on a stool and pay full
