Hii experts pls ans ..ch 2 moments the adventure of Toto ..Q- why did grandfather offer to pay fare for tortoise as well

Dear student, Grandfather was made to pay an extra sum of three rupees for Toto as the ticket collector classified him a dog and not a monkey. Grandfather took Toto out of thr bag to prove he was not a dog but in vain. Finally, just to have his revenge, he took out his pet tortoise to enquire what he must pay for him but the ticket collector said there would not be any charge as it was not a dog. Regards
