Not all electrical items 411A, just nice to bring home items like wine, meat and other stuff you and your family would like from home or elsewhere, as we live in the pit and you don't.
It's a perk, l agree, however it costs the company nothing for us to do so.
The bags weigh in at 5 kg for a start, and after minimum loading with the basics for a layover, even for just 24hrs, there isn't much left for the nice to bring home stuff with a limit like this one.
And if it's liquids you are bringing back, like wine (and there's 5 kg's for five bottles), then it has to go in the checked-in bag. Unless you can get a better deal at the duty free, which is not always the case at 90% of the ports we service.
