DS went travelling done years ago, and the last place he visited was Russia, where he stayed with a host family.
When he left them, he was given gifts that included some rather dubious home-made spirits that almost certainly could be a problem at Customs back in England. Nevertheless, they were put in his case, though he chose to wear the clearly Russian teeshirt that they also gave him.
Wearing that teeshirt, not surprisingly he got picked out by customs for a bag search. However, although they didnt know each other, it turned out that the customs officer had been to the same school as him, so after a jolly conversation about that, he wasn't actually searched.
A very fortunate coincidence!
