While working in LA county several years ago my co-workers took great amusement in all the perfectly normal things, to them, I'd never had or herd of. After one such conversation I was instructed to take my lunch forthwith, a bit rich as I was the boss, and go to the dinner on Melrose Ave and order a root beer float. As I had no idea what this was but am always open to new experiences, a policy which has lead me into tapioca related difficulty on one occasion, I complied and have never looked back.
Since quitting drink I'll happily sit drinking a root beer of an afternoon in the pub. Even though I know that the landlord knows that I know it's actually Dandelion and Burdock he gives me.
