Scenario: Tucky was keen on expanding his mechanical engineering business. Lethal Leigh knew about this and decided to offer to sell him a milling machine for $24000. Tucky replied that he would buy it for $23000 but only if it passed a mechanical inspection. Lethal Leigh was happy with the inspection but wouldn't let the machine go for under $24000. Tucky though about the machine and decided to purchase it anyway. He rang Lethal Leigh and told him that if he won't take $23000 he could go the full $24000. However, Lethal Leigh has been in contact with the local government authority and they have told him that they will pay $26000 for the milling machine. He does not wish to sell the machine to Tucky.
