I went to the hardware store because my bathroom tiles had started coming loose. The clerk said, "Ceiling or floor tiles?" I said, "Floor."

He said, "Linoleum or ceramic"? I said, "Ceramic."

He asked if I'd was going to re-glue the tile myself, and I said, "Yes."

He asked if I'd ever laid tiles before, and I said, "No."

He then produced two tile adhesive products, and recommend one because it was a water-soluable semi-solid which would be easier for an amateur to work with.

As I walked out, I thought, "Hey, that guy 'niched' me! Instead of just handing me the tube of something closest to him, he drilled down to find out exactly what I needed and why!" I wonder what his WA nickame is, LOL!
