Re: Real world?
Indirectly YES.
Succesful shops move to more desirable locations where the rent is higher.
If you have less revenue you move to a location with lower rent.
As for payment systems it wouldn't surprise me to find out a mall operator who provides basic infrastructure like heat, lighting, etc. also provides data networking and payment processing and requires them to be offered - even if you tell customers you prefer cash or e-transfer. The payment processors contract with the mall probably stipulates some kind of exclusivity to the extent it's legally allowed.
