In another thread, I mentioned not being about to find saucers at the local Kmart or Walmart. Now it's bath mats that have gone extinct.
I grew up with the kind of bath mat that is made of the same material as a towel except that it's thicker. It isn't a rug. It isn't a mat woven of tube-like pieces of material.
I still have some of these old fashioned bath mats that I got less than 10 years ago. But when I went looking for such a thing at the local Kmart and Walmart, there were none. I spoke to a young Walmart employee about them and she didn't understand what I was talking about.
