if someone threatened to ticket them they could claim they are waiting
for a customer and that they are allowed ?20 minutes for that.

In Pancras Road - the road that runs between Kings Cross
and St. Pancras stations - the waiting time allowed is three
minutes, if I recall correctly.

I have never heard of any such a restriction, but will be there tomorrow
and will check.
