My aunt was a courier in Brussels in the 90s/2000s! I visited her when I was backpacking and she gave me the low down. It was pretty funny, really boring job but she had to get security clearance, get hand to hand and firearm training. It came up because she was giving me a ride somewhere and when I first got in her car she was like “now be careful, there’s a gun here, here, here, there, there, under the seat between the seats behind the seats, in the glove box” just all over the place!!!
