@phusionphil, sorry! You need more $PIZZA to use this command.
The minimum requirement is 20.0 PIZZA liquid, and 0.0 PIZZA staked.
More $PIZZA is available from Hive-Engine or Tribaldex
Sorry, you don't have enough staked BEER in your account. You need 24 BEER in your virtual fridge to give some of your BEER to others. To view or trade BEER go to hive-engine.com
