I went through passport control at Heathrow before my connection to Manchester. It was typically annoying in a passport control sort of way (making everyone wait while some DUMBASS who’s admitted to handling livestock states his business to the only two officers, leaving none to process the passports of the 30 people in line who all have connecting flights. Logic).
So they open a new window, and I’m first up. The guy looks at my passport, looks at me, looks back at my passport, looks at me, etc. This is normal procedure. My passport photo is one of the ugliest in the world ever, and it tends to raise a red flag, since I’m so pretty in person. It was even more confusing when I was blonde. See for yourself:
