They don't even have a working chip reader and share their employees with Dunkin Donuts.

If I'm limited to eating subway and a couple other places with bitcoin versus eating anywhere I like- I'm taking the anywhere I like.

Plus, how do you price it at subway. As a consumer I like the dollar is relatively stable. Whereas with bitcoin it changes so much that in a week I could find out I paid the equivalent of $100 for a 6 inch turkey. Or when it crashes a business could find out they accepted $10 for a first class flight overseas. With cash i don't have that exchange rate risk.

I can be far more confident that my dollar will be worth somewhere around a dollar in 2 weeks.
