Yes...

I learnt about this when connecting with my UK flight at Amsterdam last month, as I was passing thru security to make my connection they pulled me to one size checked my hand baggage, put the small liquids and creams in a plastic bag and confiscated the 4200 Baht bottle of champagne brandy purchased from King Power in Bangkok
To say I was pissed off

is an uderstatement although I shut up when they said one more word and you're off the flight
What purpose is that little plastic bag supposed to serve
