The value of a bitcoin will have to become less volatile before that day comes. Compare:

Yes, the value of the dollar also fluctuates, but over 30 years it has ranged only around 30%. Whereas bitcoin has ranged 4000% in a single year. Not sure any pub would want to accept that volatility, nor would any patron.
