We were in Gruene and there was a lot of traffic (for Gruene) so they had an officer directing traffic by the dance hall. Some kid in his twenties was wanting to turn but was not using his signal. The officer signaled him to stop, walked over and told him to pop the hood. Officer looked under the hood then went back to the driver who asked "what is going on"? The officer said "just checking if you were out of blinker fluid". He then reached in and flipped the turn signal and said "nope, you are just an idiot".
