This possibly explains why he was walking at midnight. It is better to walk to a nearby pub than to drink and drive.
Drank for 2 hours at the bar. Probably walked to and from the bar to avoid a DUI.
True story: my husband and I took a walk and stopped at the neighborhood pub - when it was time to leave and the owner realized we had walked, he said he would NOT have served us if he had known that! Figured we couldn’t cross the street on foot - we had a great laugh over that one.
