I was asked to do that in my hometown with a girl I had never met before. It’s not only tourists, and it’s not only in foreign places.

BTW, that girl had to be 5% handsy with me to sell the lie, and when I met her real boyfriend that same night, he pretended to be royally pissed for five seconds and I was so scared. He laughed it off. Good guy.

I've learnt to be paranoid: marriage can be a scam.
