There is a way of dealing with this tomfoolery. Ask to see the risk assessment that underpins all these security/safety measures and then ask to see the 'fit and proper person' qualification from those who put the risk analysis together. Thing is, whilst the airport drongos are fixating on clear plastic bags and shavings of sawdust, they are mssing the planks of wood! Airport security have entirely lost the plot in respect of how terrorists can sabotage an aircraft and, frankly, the greater threat is always airside, not non-airside.
