4 because I was standing at the self-service checkout with a problem and no one came up to me, well, that is, the cashier should come up above the cash register, he did not come up. I went to a regular checkout and bought everything there, but no one solved the problem at the self-service checkout, someone else did not work there 2/2. In short, there is a shortage of employees, especially in the evening when there are a lot of people, and only 1 employee works.
The store is within walking distance, despite its small size, you can always find the optimal set of products for a very reasonable cost. Self-service ticket offices sometimes solve the issue of queues!
