Re: food, farts, perfume\cologne... whatever
Nice to hear I'm not the only one. Never mind airports, I've long avoided going into Debenhams 'cos their layout makes you run the gauntlet of a stinks department before you can reach anything I might want. Though it's not as nauseous as an egg, let alone stinkier trad-greasy foods.
I've long said we should have stinky-food-free (or even all-food-free) railway carriages just as we had non-smoking ones back in the bad old days of a more pervasive problem.
