A couple of weeks back when I took a flight from Liverpool to Amsterdam I had my shower gel, moisturiser, and facewash taken from me by security after my bags had passed through x-ray and I’d passed through the metal detector.
I had placed my toiletries into a clear-ish polythene bag that I’d tied a knot in. Okay, so that’s not the fancy resealable plastic pouch that they show in the security notices, but I could undo the knot and re-do it again, so I had figured it would be okay. Not so. The guy called me aside and with a sigh I said “I had a feeling this was going to happen.”
