Lost baggage being returned? Yep, yet another receptacle in which to place an unauthorised package. It seems that because it is allowed to happen, that makes it alright.
Having just had my shoes taken away and given the second degree: my laptop put on the sniffer machine for 5 mins. The same big case first mentioned, went through still carrying electronics test gear. Of our 4 cases, this was the only one not opened as denoted by leaflet left inside.
