Weird dream...
I dreamed this morning that I was in some large restaurant/advertising place, and next to me on the wall/table/divider was a bottle marked "Scrumptious Reagent" (if you don't get the reference, see
Kingdom of Loathing) and I asked the guy who worked there how much it was, and he said there were 20 servings in it, and the whole bottle would be $20, so $1 per serving/cup. (It wasn't a huge bottle, so apparently - I assumed - it foamed or something to fill the cup.) LOL!
