You remind me of a kid in a computer store years ago. He told me he was

That depends entirely on what the mat is made of.

Rubber matting with conductive carbon particles
in it, can conduct. The matting might have a
resistance of around 1 megohm, which is ideal
for static electricity dissipation.

What I've learned over the years, is looks can be
deceiving.

All you have to do, is find the person who *paid*
for the fancy item, and they'll tell you the
magic properties :-) "It'll burn a hole in your wallet" :-)
That's one of the magic properties.

But then we have to consider the composition of his shoes, the floor
material, and the building. A wrist strap to earth ground seems easier.
Probably cheaper too.
