A question that the OTF will sure answer! I don't know how to really ask this question to my friends so I'll so pose this question to the OTF, since I know more than one person knows the answer. Say I walk into a bar and order a drink, how does paying the bartender work? Do you pay in the end, after the totals up how many gallons and gallons of Canadian water did you drink. Or do you pay as you go?
