It feels okay! Depends on the crowd you choose, as long as you do a good job, the price is reasonable, the consumer crowd can accept you this price, so this is also an important factor. In my school neighborhood, there are many stalls selling snacks at noon. One of the big sister is very smart, she sells already made potato cakes. When the end of the school day came, the children swarmed out, all running to the front of their favorite snacks to buy snacks. There were a lot of students gathered in front of her stall. She puts the potato cakes on a plate, spreads them with homemade sauce, sprinkles them with cumin or chili, and puts them in a bag to hand them to the students. After a while, only six or seven potato cakes were left.
