In 2010, we hired a contractor to extend our kitchen to include one small room for storage. The agreed price was 500,000 pesos or roughly $10,000 at that time. The contractor asked for a 50% down payment so they could start working. And they did work upon receiving the money. However, when 1/4 of the job was done, the contractor was again asking for an installment. Oh, wait a minute. That's 50% of the cost that we gave and they had delivered only 1/4 of the project. That's unfair. Sensing that we are being scammed, my husband rescinded the contract and hired carpenters to finish the job. The work was done in a month and we had some of the budget left for us. In other words, we had saved money.
