Wow. It's all about spaghetti with you folks huh. Well plot twist! He has a new get-rich recipe for pie!
As usual you hide and listen the the passwords, this time to you decide to make a chart:
"10" -> "5"
"6" -> "3"
At this point your friend has had enough. He's been taken by security, trampled by elephants. He's tired of you being the one to get in. He tells you this will be the last time he goes for that recipe! He walks up to security and they give him the number "2" he whispers the number in their ear so you can't hear it and he gets in. Traitor!
It seems you arrived late and only got to hear 2 guests! So you walk up anyway and get the number "14" what's your response?
