As far as PAX are concerned the answer must be Yes sometimes.
For example, I have to check out of the hotel in the morning. My overnight case sits under the desk all day at the client's premises. I leave the desk for meals and breaks and meetings. It is locked - for what those puny locks are worth.
When asked the question, I say that it was attended.
Why?
Because the chances of someone being inside that building AND spotting an overnight bag AND finding out that it is going on an aircraft AND putting something nasty in it ??? So, when I put my papers and PC away, I have a quick flip through to see if there is 'jokey' stuff from a colleague.
Not ideal, I know.
