Capgemini — unnecessary paid fine

I get in bmtc bus from beml layout whitefield. The conductor was already in gents section he was giving ticket to someone. I and 2 girls asked for ticket. As we know he can give one person at a time. Money was in my hand and he took money from one girl he was about to give ticket. Till now the next stop didn't come. Suddenly people came for checking. Conductor told about me and remaining girls that just now they came in.
Still they asked us to pay fine. I explained him this is the situation. But they didn't try to understand that situation is right or wrong they want only money. At last we paid.

This is not the way to charge fine. It was not mistake from our end.
