<i>&quot;Somebody revising a quote doesn&#x27;t mean they were lying the first time around. You may not care for negotiation, but that doesn&#x27;t mean it is dishonest.&quot;</i><p>There is a divergence in moral values in here, and even if you think someone should accept a certain view on negotiation, it is, however, especially when there is no visible benefit at all for them, their choice to refuse to do so. The commerce has on its core the idea of mutual benefit and this haggling-justling violates the sense of mutual benefit. It is only natural to expect less trust from your &quot;customers&quot; when you&#x27;ve treated them this way.
