In my personal experience, it is recommended to do supermarket cashier, I have been in the summer in the catering industry as a waiter for two months, in the store basically required to stand, customers on call, can not play with the phone (cell phones are to be handed over), the receipt of the table, the dishes need to waiter, morning and evening before the opening of the need to tidy up the health of the busy time to set up the table a day to receive more than 90 tables, very tired. My relatives have a supermarket, I also collected a few days for him, feel a lot better, the main cashier does not need too much running and cleaning up, compared will be easier. Of course, you also need to choose to compare the salary, the salary is about the same you choose cashier it. I hope to help you
