The only thing I like about my credit card is that it’s more protected from fraudulent transactions than a debit card. That means I’ll use it for random gas stations and the like, but anywhere I know I’ll go out of my way to avoid it.
It’s total bollocks that financial institutions managed to insert their own tax into a huge portion of consumer commerce, let alone how badly they take advantage of the financially illiterate and the desperate. There’s no reason credit card merchant fees should be so much higher than debit card merchant fees, but they are.
