The great shortcoming of supermarkets that nobody talks about

It was a time when going shopping, including stores with diversity of products, involved interacting with the seller. You asked for each article, the seller took it from the shelf, pack it individually and bought it.
The purchases, obviously, had more, more, and the business was – as obvious – more expensive, because it needed more staff.
Through the 1920s, self -service stores began to appear in the United States, and the model entered Europe through the 1950s.
The stores of those times are the ancestor of the supermarkets today, from where not only do we take each other everything we want from any shelf, but we can scan every product, we pay, we leave, ready to buy.
There are, for many, many advantage of the buyer from the supermarket, especially in the big cities where the rhythm is rather infernal, so we want to solve things-such as purchases from one place-as quickly as possible and as little as a headache.
There are, among the shortcomings, an apparently anecdotal one. Read, on B365.ro, which is this.
