A friend of mine told me the other day...
She'd gone throught staff search at LGW N and had her bag searched. She was told by the woman who searched her bag that she should put her camera in the hold, as cameras aren't allowed airside (the woman obviously didn't have a clue). My friend burst out laughing because it was so ridiculous. She got reprimanded by the woman for laughing.
Unfortunately this is actually true .... while pax can snap away happily staff at most major UK airports are not allowed cameras airside without prior written permission.
The rules have existed for ages but only recently have been enforced for some reason ..... perhaps it had something to with airside tours being posted on u-tube after being obviously filmed from a catering vehicle
Annoys me as I quite liked to have the camera with sometimes.
Of course, as with all well thought out rules
..... they apparently haven't thought what to do about mobile 'phones with cameras
