So instead of the restaurant paying about 10c to process your credit card (and you getting about 1c in Credit Card points), you paid about 5c on top of the bill.  Via coinbase, they pay 0% fees to sell the BitCoin to them instantly for $$ (first $1M) 
No wonder businesses are interested, 0% chance of chargeback, and the customer pays the fees.     Unless the businesses gives you a discount for BitCoin purchases, it's not to your benefit though.
