Around here it is quite common to do with dairy products.

I however choose not to do so quite deliberately. I want to avoid food waste. I just check the date is "good enough". My regular shop has a good enough flow that I usually pick from the front.

Food waste is a trending concern around here. But I think you and I who cares about shelf life belongs to the same minority. The majority has enough other worries and does not spend bandwidth to care as it is usually good enough.

I consider fish a "fresh" item and care more for looks and smell.

Same as with vegetables. But I hate people who prod everything - that is detrimental to the product.
