There is no 'breach of contract', any business can perfectly legally refuse you service or delivery and choose to refund your money. How do you not understand this? Hell, a gas station can refuse you to buy a pack of gum if they feel like it. Nothing illegal about that unless they refuse you based on race, gender or sexual orientation.
"Refusing" a purchase is very different than accepting payment, failing to deliver the goods, raising the prices, and forcing a refund on a customer. While it may not be literally illegal, it is scammy.
So you go to a club .. you pay your entrance fee - you behave like a dick. You get thrown out - NO REFUND. This is the proprietors fault somehow?
