that pumped the first 10 gallons accurately then cut the gallons short after that? When the county auditor checked the pumps for accuracy they filled a graduated container, they did not go over 10 gallons so they missed the scam for years.

就是在前10加仑计量准确，之后却少给加仑数的情况吗？当县审计员检查加油机的准确性时，他们使用量筒注满，但没有超过10加仑，因此多年来错过了这个骗局。
