If you look closely at the picture, you can see the reflection showing that this was taken from inside the store, and see the sidewalk outside.  The question is that if this door leads to the outside, shouldn't the sign say DO NOT EXIT instead of DO NOT ENTER?  DO NOT ENTER?  Enter where?  Enter what?  Enter the outside?  I mean, I'm in the building.  What would I  be entering if I went through this door?  Walgreens has two doors and they want to direct traffic a certain way, but it would be nice if it made sense.  But I guess I'll just exit without comment (or is that enter)?
