Just returned from a quick RTW jaunt and it would seem every country has it's own security quirks.
Worst was DRW where we had a small packet of face wipes (a bit like wet ones) confiscated. Apparently the packets must contain 10 or less wipes to be allowed on board (ours was a packet of 20 of which 5 or so had been used). The packet of wipes had been around the globe once already and travelled internationally at least 6 times.
Seems a bit petty to me.
