Difference in culture!
An Indian went to Japan & being his regular habit of resting the feet on opposite seat, he did the same while travelling in a train.
An elderly man came to him, took his feet onto his lap and sat on the seat. The Indian was awestruck.
He asked the gentleman "Sir, why did you leave your seat & come here to keep my feet on your lap and sit?"
The man answered, "mister, you have insulted us by misusing our public property. I was very angry at you for that. But you're a guest to our country. I cannot insult you in public. You are habituated to rest your feet on the opposite seat of bus or train you travel. And I cannot see my country's property being misused. So in order to save our public property & at the same time not to cause inconvenience to a guest, I took your feet on to my lap".
