Seriously, you want to change pancake mix? Use some buttermilk instead of milk. Mix in a bit of sourdough starter. Add some fruit. Cook down a can of fruit with some sugar and lemon juice and make your own syrup. There are tons of things you can do.
If I go to a fancy restaurant that specializes in pancakes, THEN I expect them to do their own thing. But waking up at morning and getting pancakes that someone has prepared for me is better than waking up in the morning and eating a bowl of cereal or a pre-wrapped muffin. MOST people don't have a go-to pancake recipe... they'd just look up and use the first thing they found online that they had ingredients for.
