First of all, let’s try to avoid American-bashing, and stay respectful to everyone.
I’ll start: for me it’s the tipping culture. Especially nowadays, with the recent post on [email protected] with the 40% tip, it just seems so weird to me to have to pay extra just so that menu prices can stay low.
How is A an unknown? They’ve demonstrated that they don’t make a habit of spending money they don’t have, which most people would consider conservative and responsible.
I agree that credit scores are stupid, but for the purpose of playing the devil’s advocate… Person A may have just crawled out from under a rock (or their parents’ money) and knows not how to manage a credit or just thinks it’s free money. They’d still have no credit history. For risk assessments, you always take the worst case in all fields where it applies, not just financial.
On the other hand, I think that if your circumstances change and you manage to pay off a loan early, you get penalized on your credit score, cause some bank had plans for your interest for the next 30 years or something.
