Perhaps it’s worth naming and shaming those agencies on here that HAVE a policy of “If you turn up, and we forgot to cancel - you get paid” that then gets side-stepped when it actually happens because the CUSTOMER forgot to cancel… and has a conversation with the agency similar to this:-
“Look bud, we’re not paying for your wasted-time bod. If you press us - we won’t use your agency again to block book the huge number of drivers we take from you otherwise. Learn the politik here - and let the client get away with murder, as can you really afford to cross US?”
Supermarkets especially are guilty of acting like this ^^^^ of course.
