They had an interesting counting thing at Euston a few weeks back. Any
time you entered any station entrance or came off a platform, you were
given a card of a certain colour. When you left the station or entered a
platform, you had to drop the coloured card into a box.

The idea being too see how many of which colour ended up where.

Nifty!

Of course, most people either immediately chucked the cards on the floor
or didn't remember or think to give them up when they left, so I'm not
sure what success rate they had in getting the cards back.

Doesn't matter. They just need to compare the number of (eg) red cards at
location X with the total number of red cards collected. Those that just
get chucked on the floor can be ignored - assuming that the probability
of being thrown on the floor is not dependent on the colour.
