Is leaving coffee bins open in the store normal? I'm checking out a local coffee shop online that was recommended to me, before deciding to go in. I noticed that the beans they sell in bins are all uncovered in photos (the photos are from Google so they're most likely taken by customers).

Is this normal for coffee shops to leave beans exposed to air like that? I was under the impression that air exposure directly affects flavour. The place has fantastic reviews and a few people told me about it IRL, so it seemed odd that they wouldn't follow what I would think is standard procedure.
No, it is not.

As you may see in many other answers in this SE, Coffee SE site's answers will lead you that coffee is best stored when it's distant from air,  odor and light.

Closed, vacuumed storage is the regular way and coffee stores are no exception. On the other hand, one may expect that a store should grind coffee when it needs it. So, it won't go stale unnecessarily.
