I once played in a LARP where one of the characters backgrounds was from a culture that emphasized the importance of trade and had established a number of rituals around the trade and barter of goods. Some examples being:

• Haggling usually occurred over a freshly brewed pot of coffee made by the seller, the quality of which would set the stage for who had the upper hand in the barter.
• the buyer would usually tell a story about how their acquaintance or distant relative got the product for a better price in another city and the seller would inevitably tell the buyer how much time and effort it would take to get to that city to get the same price and how their price is worth the difference.
• Both parties would tell complete, but almost believable lies to claim the price should be higher or lower, but it was polite to interweave their lies into yours such that directly disproving either parties lies would make the points of both parties crumble, as to discourage that

It didn’t, like, get me hard or anything, but it was a lot of fun to spend most of the weekend hawking fake goods and telling stories of “far away lands”.

So like I half get it. Not entirely but just kinda.
