The storefront is entirely glass and very large, unlike most other businesses. It's common to have bollards installed in front of them. Even large stores that have fairly normal entrances in walkable areas typically have them. I actually can't think of a store near me that doesn't have them.

I don't see how a case like this would necessarily apply to every business establishment everywhere. There's clearly an added safety risk due to the design of this store in particular.
