I'm on the same page as everyone else here.....I still remember growing up in a small town, probably 10% the population of AC. Mom & pop grocery, gas station, hardware, bar, etc....they all ran tabs. Extremely rare for anyone to get stuck and there were NO interest charges. I know - my family owned 2 businesses and I worked in a 3rd. We all took care of one another when needed. Good to know there are e still places like Marina's. I knew there was a reason I liked that store!
Some dated, but probably still valid, info on interest charges, banking etc. in BZ here: http://www.google.com/search?hl=en&q=usury+rate+belize
