I've paid several times in bars and restaurants with bitcoin (I go there especially because of bitcoin) and every time I was ripped of.
Every time I paid a premium of 5 to 10% above FIAT price when I paid in bitcoin.
If bitcoin wants to succeed as a payment in bars and restaurants this really has to change.
The reason I did it was to show the experience to friends whom 'I sucked into the bitcoin sect'.
Now I showed it to them all and I'm not going to use bitcoin for these purpose anymore untill the price is equal or cheaper.
Do other people have the same experience?
