Agreed. I haven't yet come across a case of a gate opening when an
Oyster card is presented without the touch-in or touch-out
registering.

This happened to my girlfriend the very first time she used Oyster
(Actually it was the second time she used it as it was the exit of her
very first journey from Euston to Watford Junction).

It also happened to me once, at Amersham. It just confirmed my
suspicions that Oyster is at best a useless white elephant, and at
worst a force for evil.
