My present vocation is very meaningful, but my favorite job was working as a Page at the large, main public library for two summers during college. I love being surrounded by books. Libraries are still special places for me.
I suppose this is better than a bunch of sullen employees who ignore you. But how about a middle ground, like a simple, pleasant head nod to acknowledge your arrival? I just want a sandwich, Subway, not a new group of friends. This policy is clearly the work of extroverts.
