It would be cheaper just to put out a sign “Free Beer”. It would be gone without labout within the day.
I lived in St Joseph Missouri in the 70’s and we had a Pearl Brewery in town. They had an underground warehouse to store their products. The Missouri River got wide one year and flooded the basement of that brewery. The water according to heath standards contaminated the beer containers. Cases of beer got condemned to the dump in St Joesph. Well I worked at a coal fired electrical plant down by the dump where the beer was buried. Most of the containers were broke but some survived. The hobos and derelicts down at the rail yards near the dump dug for the treasure. Free beer is a real thing. We all laughed about it drinking draft beer after work at the South Town Tavren or Hap’s. Seems like a hundred years ago. Just shows to go ya, history does repeat itself or stutter. 😊
