But rules is rules and if I as a member of the public have to do it why shouldn't staff etc.
1) Because, sometimes, we have to do it several times per day.
2) Because we have been security screened to be able to work airside.
3) Because we have better things than a belt at our disposal if we really felt that way inclined.
4) Because my belt didn't set off the machine last week, the week before or any time in the past.
5) Because I only have a limited time to get to the aeroplane before a delay is inevitable, and removing my belt just adds to the time it's going to take.
6) Because there's then delays at the other side of the security gate where everyone's replacing their belts.
