Some players refuse to play chess with clock!


Some people I know, C class mostly B class players want to play for $$$ BUT without a clock whatsoever, they say they are not familiar with it or don't know how to use it etc...
So my question is would you still play someone for $$$ if they refuse to use the clock?
They are rated B or C and don't know how to use a clock? It's so easy to use - show them and make sure they press the clock lever with the same hand with which they moved the pieces - otherwise what's to learn? It taught my 8 year-old nephew how to use it in less than a minute. If they won't use a clock, I wouldn't play them period.

They are not B or C players. They are probably not even D or E players if they don't understand the concept of or how to use a chess clock.
By definition, to be a B or C player, you have to have played in official FIDE or nationally sanctioned tournaments where there are clocks. Unless you're talking about correspondence, which has move time limits in days.
