When people leave their vehicles ( especially large ones ) running while eating , waiting , or other reasons . We seen several different people do so in fast food parking lot . One letting his S.U.V. run for over 15 minutes while waiting for someone in Mc D's ( still running after we left ) and a few young mothers coming out of Mc D's and then putting kids in car and turning it on while they had a cig outside of car . Even worse we've encountered many letting their vehciles run while pumping gas . Most have been under 30 . What's your take on this ? ;- )
