A citizen of Jinan, Ms. Jia found that a bottle of sesame oil purchased at the supermarket had an abnormal taste, but the product did not expire. The supermarket staff believed that there was no quality problem with the sesame oil, and Ms. Jia was willing to return the goods unless she had a legitimate quality inspection report. I found the Food Center of Jinan Quality Supervision Bureau. The other side told her that the testing fee would cost several hundred yuan. Ms. Jia said that this bottle of sesame oil is worth 13.5 yuan, and the inspection fee would be several hundred yuan. Travel expenses, time, and energy are really worth the loss. For this reason, Ms. Jia had to throw the remaining sesame oil into the trash can and no longer complained. According to this article, what is the correct understanding? ['There is no clear shelf life for sesame oil.', 'Complaints are expensive.', 'The average consumer will not write a complaint.', 'Ms. Jia complained that she did not find the right organization.']
