"We did not publicise the change as research indicated that very few
passengers would be changing their normal practice of hailing and
ringing the bell."

Thank you for explaining why the bus I was on yesterday did not stop
where I wished to alight. It never occurred to me that the advice I
recall being given on buses as a child in East London in the 1950s not
to ring the bell [1] for a compulsory stop had changed.

[1] The language of the clippies was rather more colourful and
compelling.
