Sorry, should have stressed, not the Accountants fault in all cases. Have definitely observed many cases recently where client just will not give the information, despite being chased up many times. Have also observed cased where Accounts left till last minute and then client gone on hols/etc as what happened here.
Also have observed what others say here, Couriers here, there, everywhere, picking stuff up at weekends, etc.
Of course it is to do with the Audit Exemption.
