In the restaurant next to the supermarket, because of the supermarket next to it, the passenger flow is quite large, often full~ and many restaurants here are the same model, divided into 2 kinds of dining, one is a buffet, the other is an order-style~ all are cashiers first payment, buffet form, Just go to the buffet area to install food, don't waste food~ There are not many self-service choices, and the taste is more general~ The quality of the nationals in Finland is still quite high, so the merchants still believe in the diners, basically relying on self-help, No one supervises it~ It is best to clean up the plate after the meal and so on~
