On initial glance, it appears the guy holding the iv bottle, if you look at it, it looks like a drink that’s salted on top.
I’m guessing that’s what he meant.
Never crossed my mind even swilling 100’s of salted Margaritas straight up but maybe because I had 2 high school buds from my very small town killed over there in a short period of time 65/66 and to view the pain and anguish only reminds me of what they may have gone through.
