You were supposed to go by bus to your friend's wedding, but on reaching the bus stand you find that the only bus you wanted to catch is just to start and there is hardly any time for purchasing the ticket. The best thing for you is to
1
rush to the bus rather than miss it and inform the conductor about your inability to purchase the ticket.
2
rush to the bus and starts arguing with the conductor to get a seat
3
first, purchase the ticket and then catch the bus.
4
miss the bus rather than take the risk of boarding the moving bus.
