Same as the people who tut at waiting in line for shopping, then when they get served and the checkout asks for the money a look of horror comes across there face as they start to fumble through there belongings like having to pay would be the last possible outcome when shoppingThose people on a bus that can`t just "get on with it".
Surprisingly you have to pay by some means when you get on, you could have furtled for your coins/phone/bus pass whilst standing at the stop before the bus arrived.
They are also prevalent in shops, banks and anywhere else you just want to get in and get out.....
In such cases queue jumping should be permitted as I am pre-prepared for my transaction.....
