50 cent a can? When I was in HS, it was 99cent a six pack, and it was still overpriced.
I went to HS with a guy who later became sheriff there. He was lacking in brain cells in school which hadn’t improved years later. Heard he went into a convenience store and brought two six packs to the counter. The clerk told him a 12 pack was cheaper but he said he couldn’t drink 12 beers.
