JayJuanGee : I'd say what matters most isn't the denomination on the bills (although that might matter if you're hiding money from the taxman) but rather what basis the business is using to price its services/goods. If the basis is fiat, which it will almost always be, then even if you can pay in BTC, there will be favorable and unfavorable times. Of course if the business is also trying to hide some income from the taxman, then some deals could be obtained...
