Yes you have a vaild point. Charge per kilo on Buses.

Surely it is NOT unreasnoble for people taking up 2 seats to pay for them. I think in a lot of American airports they weigh people in.

This is also important for safety purposes as the freight is weighed and changed at last moment if more or less passengers arrive . But surely weight of passengers should be taken into account.

Surely the big ( pun unintended )question is why so many get so big nowadays. How much is this costing The NHS.
