In my town (which never reached full prohibition), the same impulse which led to repeated prohibition votes and local prohibition, also supported the big ‘coffee palaces’ and one well-known ‘soda fountain’ (based, I guess, on the American model. Were soda fountains ever a European thing?).
On the other hand, my ancestor in Michigan apparently enjoyed the odd ice-cream-in-beer with his golf buddies. His son would get a root-beer float at the same time, which I suppose was the cover story.
