The small size of the store, but the administration is not to blame here.
There are moments of significant accumulation of customers, and only 2 cash desks are open. And it would be good to introduce cumulative discount cards, as in Tavria, so that small change is postponed to them, and cards are issued for a one-time purchase of 200 or 300.......hryvnia. The availability of such cards would speed up and facilitate the work of cashiers.
