Varna's a city in Bulgaria right next to Romania.  I was there visiting relatives a couple of weeks ago.  That golden Panda symbol is in a lot of cafes and shit where Romanian tourists hang-out.  I watched people do it, same deal with the e-mails like the other dude said. You get a 10% discount.  All I had was a bunch of Bitswift they gave us and it was stupid to try and sell Swift for Panda on a phone just to buy coffee so I just used normal Bulgarian money.  

I also saw some Panda Expresses in California that take Panda and Doge.  Kind of weird using Dogecoin to buy food at a Chinese restaurant.  Panda made more sense.  It wasn't ghetto like Bulgaria.  They had some kind of scanner but the girl at the counter at one place said they were having trouble getting it to work right all the time.  I should have taken a picture but all I cared about was chomping down some potstickers LOL.
