That's an incredible read...
So maybe one has to test oneself now in case the hotel is trying to shaft someone, or a hidden camera film crew is trying to shaft someone... or a receptionist at a hotel gets dumped by a pilot....and guess what... yep she's going to try and shaft him (or him/her) it really is getting silly.
I don't think it will be long before pilots check themselves out before report to be sure (even if they were being extra careful thinking they were drinking nothing 24 hours before). I understand that some airlines now have random testing of crew (not CAA/JAA) but the actual airlines themselves. Searching on google for breathalysers brought up a few products, one company of which is now advertising here on prune -

So even as JAR says, the prudent pilot should not drink 24 hours before a flight it would not have helped the above story if they were slipping him something!!
