should put up a poll but the consensus seems to be NO. tiny profit margin, super long hours, and high turnover rate. this doesn't include all the advertising you have to do, fliers/pennysavers/church ads/local radio, losses from coupons. often times you need to donate/sponsor to your local community (little league, schools).
big thing though, you have to run this place like a business, fuck loving it. you'll end up giving away half your inventory if you go into this business cause you love ice cream.
