Probably not as great but still a factor that needs to be considered -
especially at peak times where buses can be full or already have long
dwell times in Central / Inner London.

Out in the provinces the existence of "all day" tickets (typically around
£4) means people only have to pay once, and combine that with an "exact
change only" policy and it's quicker overall than having people fumbling
in their purses to find their bus pass.

Providing of course later buses are signed up to the all day tickets. Many a
traveller has tales of being caught in a suburb or satellite village and
finding the only buses that turn up at that time won't accept the already
purchased ticket. And this information isn't always easy to find online.
