What do consultants do in supermarkets?

Neither consultant nor counter salesperson enjoys the benefits and promotion opportunities in the supermarket, because these two positions are employees of the merchants stationed in the supermarket, belonging to the employees of the merchants, not the supermarket, but working in the supermarket. And merchants and supermarkets are just cooperative relationships. Just like you go to the market to sell chickens, you are an employee of a chicken farm, not a bazaar.
