Last one night, a police officer was waiting outside a noisy bar to look into possible bad behaviors. At closing time, a man walked out unsteadily, fell off the sidewalk, and tried his keys in five different cars before he found his. Then he sat in the front seat trying to start his car for quite a few minutes. Everyone else left the bar and drove off. Finally, he started his engine and began to pull away. The police officer came over, stopped his car, and asked him to do the breath alcohol test. The test results showed a reading of 0.00. “This is strange,” the officer thought. He wondered how that could be. The driver replied, “Tonight I＇m asked to act as if I am drunk. Now they are all safe!”The police officer wanted to have a drink.
