The conversation started with a simple warning from someone whose wife received what looked like an urgent domain renewal notice in the mail. The panic was real - business domain expiring! Must pay $265 immediately! - but the threat was fake. What followed was a fascinating discussion about how these scams work, why they persist, and what we can do to protect ourselves.

This particular scam is apparently as old as paid domain registration itself, dating back to 1995. The mechanics are brilliantly simple: send official-looking mail to domain owners claiming their registration is about to expire, charge an exorbitant fee (often 10-20 times the normal renewal cost), and hope people pay without checking. The scary part? It works often enough to keep the scammers in business for nearly three decades.

The other day, I spotted a peculiar sign at a coastal restaurant that made me do a double-take. A surcharge for every payment method? Not just the usual weekend or public holiday loading, but an additional fee regardless of whether you’re paying by card or cash, any day of the week. Something didn’t add up.

Let’s break down this mathematical creativity: 3% surcharge on weekdays, 10% on weekends, and a whopping 20% on public holidays. All this before you even decide how to pay. It’s like being charged extra for the privilege of… well, being a customer.
