Well, you gotta admit...it is rather exclusive, requiring a special trip to skid row to obtain.
Not available in ordinary package stores!
7-11’s carried it in every store in our city.
I read that it was originally marketed in an unusual way. Marketers would drive thru urban neighborhoods late at night and toss empty bottles in great quantities out the windows. The sight of all those empty bottles gave the residents the idea it was popular stuff that they had to try for themselves.
