Any suggestions, please?

It's worse than that. The supplier basically just shakes the electrons
at you, like tassels on a ????

According to <http://en.wikipedia.org/wiki/Electric_current>
"For example, in a copper wire of cross-section 0.5 mm2, carrying a
current of 5 A, the drift velocity of the electrons is of the order of a
millimetre per second."

So in an AC circuit, the electron would get about 1/100 mm or 10 µm
before it turned around and headed back the way it came.

I suppose the good news is that you get to keep your own electrons, that
were inside your coffee maker the whole time.
