In the past, many towns and neighborhoods had rigidly separated businesses. It was not uncommon to find towns and areas with one bookstore, one grocery store, one coffee shop, etc. However, as time has gone by, our ideas about what individual business is has expanded and changed.
Today, we almost expect to find bookstores that carry music, and grocery stores that serve coffee. Increasingly, we have come to expect everything in our lives to be multipurpose to best suit or needs. That is now even true when it comes to the world of medicine.
