I sort of see the question about "why not" cause it means it doesn't have to be the bartender. So why not choose a plumber, the lawn mower man, the painter etc I think you see the point.Thanks for the like and good question. I chose a bartender for the tryst as a way for her to be more stealth-like in her cheating. A bartender is an unknown. He’s not in the social circle at their club like the instructor. I would bet every husband that has a wife taking tennis lessons knows who the instructor is and what he looks like. It does create a loose end to cover with the instructor, but she can always see him another day /time.
The tennis instructor is too obvious.
Is the original question asking for something more secretive, more sexually daring exciting....story.....a mysterious man of some sort that she is secretly meeting up for daytime trysts?
