A friendly guy walks up to me like he's my friend. After a short talk, he gave me a nice bracelet and one I can give to my girlfriend... and then he asks for money. I returned the bracelets immediately.
I already know this scam well and how it works, but social engineering is no joke.

According to the Trump administration's own formula, the tariffs should have been four times lower.
φ should have been closer to 1 - not 0.25 - for their formula to match the actual tariffs set.
