Often ticket inspectors target interchanges and stand in the passageway
checking them. AIUI there are usually uniformed inspectors with
plain-clothed ones behind so that those who turn the corner, spot the
inspector and then turn back are also caught

They appear in the AM peak in the passageways at Bond Street on a very
regular basis. They've normally been too busy taking down the details of
A.N.Other to even check my valid ticket!!
