Hahaha. If you ask me, if those two were my friends I would get two pairs of boxing gloves and tell them to bet for themselves and have a boxing match until the other man surrenders.
This is the typical saying here if someone wants to fist fight but they really don’t want to fight in reality. Just an ego taunt but really afraid to get hurt. But we have this kind boxing tournament during our festival which many participate just to cool down with their personal conflicts.
It's actually a very laughable situation because why would anyone ask for some of his/her money back if he/she lost the bet? The lesson there is simply - Don't gamble if you're afraid to lose some money.
I honestly do this, we usually play poker with my friend then later on just purchased our total profit with food and drinks that we share together. The gambling part is just to decide who will gonna treat us with our meal for that day. It’s really fun as long as you don’t use money that you can’t afford to lose.
