In HS I used to work nights at an A&W.. best damn root beer. They sold it by up to a gallon. It was beautiful. They made the ultimate combo of soft serve, and root beer blended like a shake, called a ‘cooler’. Dear gawd they were superfluous looking back, but man they were culmination of two things combining and the result is the best parts of both.. a root beer ‘float’ u can drink with a straw.. flipping genius.. sorry for the trip so far down memory line street boulevard…but my brain went there real qwik… and I smoke herbal supplements from time to time
