@sumudu Heathrow. The most disastrous I've seen since one time I took the Eurostar — can't remember exactly when now. The immigration officer asked if I had anything to declare, and I said I had only 1L of alcohol; he then went off to ask 2 other officers if that was within the duty free allowance. In hindsight, I should've just said "no" just to save myself the pain of dealing with these imbeciles).
