&gt; As experiment shows, this is not the optimal strategy, so I don&#x27;t see why you would call it the &quot;rational&quot; one.<p>It&#x27;s rational because if Bob accepts an offer for a positive value of money, even if it&#x27;s a cent, he gains value from it. Rejecting it just throws that cent away, which he could have had in his pocket, it&#x27;s irrational to throw away this value.<p>There&#x27;s a difference between rational and optimal for a reason though, but you need to feel like you&#x27;re getting ripped off for that to come into play, you need to feel like you&#x27;d rather someone else lose $0.99 than you gain $0.01.
