Why?

So the question I pose is not, "Why does this area exist?" It is instead, "Why do we need a sign reminding us what is not allowed in there (keep in mind the lactation area should be in a clean area, one would hope) since, in theory, that stuff is not allowed in ANY clean area?"

'Course maybe it's just a nice reminder not to walk in if you don't want an awkward encounter. Especially if you come bearing bad stuff.
