for example, shopping.
without profit motive, no need to entice people to buy what they dont need, so no adverts. no black friday sales. instead of requiring consumers to walk the aisles, workers (or robots) could get things from stockroom. stores could be placed around the city for easy pickup or home delivery. no need for flashy, wasteful packaging to attract consumers attention. "shoplifting" becomes irrelevant, so no security cameras. etc.
