I used to get very irritated (10 years ago) when frequently checking IN in Gatwick to return to DUB, as a particular female regularly pulled me over for a frisk search almost every time. It was only this year that I discovered that I have metal clips in me that were part of old surgery. I thought I had been stitched. (take whichever meaning you like!)
On a visit to Melbourne, the lovely beagle showed a lot of interest in my wheeled laptop bag, which led to a brief chat on the spot, but it became clear that it was the aroma of peppermints that always permeated that bag that had attracted his nose. No peppermints, as I was very careful for all Oz arrivals, even interstate.
