Kopeyka shop and shelf life of products

I saw some posts with a similar theme, so I decided to also tell a little about the Kopeyka shop. It happens in Yaroslavl.
Some time ago they wanted to buy one of the pies that were sold in a penny, and my friend is quite sensitive to the inscriptions about expiration dates, which cannot be said about me. So, having looked at the expiration date, we noticed that some of where it is fixed (like even a simple black ballpoint pen), and some where it is simply erased (a plastic wrap, like a package, is therefore possible). Well, we, of course, were just in shock, told the sellers about it, they said that something like sorry and sort of removed.
The second time, I almost did not buy the juice with an expired date, which was also told to the sellers. Not to say that they were surprised, well, and so rudely said, "well, yes, right now, we remove ..."
And today we again see products (marshmallow or something), on which another one is valid for the actual expiration date! Stripping off the sticker - you can see that the product is expired. In general, today is Friday, on Monday we will try to draw the attention of some authorities to this. It seems like you need to call the consumer rights department. Let's hope that not everything in this world has been bought yet, and they will fly in and they will think ... After all, this penny is located in a remote area, where many elderly people live, who cannot read the shelf life simply because of vision problems.
PS Be careful.
