my guess is you guys are figuring a way how to help greek economy to recover through the blockchain somehow? Maybe Steem related, maybe with another new project.

My second guess Is you are considering ordering another round of drinks

Third guess is you are deciding weather to take a cab or an Uber to get back to the hotel...

Another one could be you guys are discussing how big a tip you are going to give to the waiter/waitress

:D Thanks for the giveaway @onceuponatime
