Why is this a surprise? A business owner speaks his own money. A "non-business owner" means "an employee of another business" who doesn't care about anything but clocking out at 5pm and not getting fired - they are totally not interested in stirring trouble. It's just a metric of them not caring, not of them being "better clients". And representing bigger and richer entities than those where a business owner is a point of contact, meaning whatever money is/was at stake is usually not worthy of bothering.

Naturally, it is a lot better to work for richer entities with less control and attention over money spent, milk the fat cows.
