I think I would have had all the water drains open for samples.
Which reminds me of an American rig on the blower to Schreiner ops Rotterdam requesting permission to send in some samples on the next flight.
Schreiner ops reply was that was fine as long as they were all dead!!!!!!
Bemused silence from the rig. (Dutch for sample being monster).
As the late Frankie Howerd would have said
NO, Oh well please yourselves
