I'm 67 years old. When I was younger, I can't remember a kitchen that didn't have a slight raised bulge at the edge of the countertop. Because of this, no water ever spilled off the counter. Today, I can't remember seeing that type of counter for years, and when I mention it, everyone says how annoying it is when water spills off the counter.
When did the raised edge disappear, and why? Please don't tell me it was to get cheaper counters.
