The Lidl branch I most use is at Clapham Junction. They have number

Why don't they just read the number going in and the number going out,
which is what my local Lidl does?


Which fails as a technique if they miss you going out. They might then
see a going-in one day and a going-out the next - and assume an
overnight+ stay.


That would require a failure of both the outgoing capture on the first
day and the incoming capture on the second, which would be a very low
probability event.
