I'm not Asian, but am curious to know why the word Asian is relevant in your post?
“Funny enough, but this reminds me almost exactly of what I was asked to do while working for a Jewish husband and wife duo.”
I guess it does add more detail.
Unless race is relevant to the story, it should be omitted. I’m sure there are plenty of other details about the couple that could be mentioned if you need to spice up the story.
"What do you have against short men?"
There's no life to the story, it's to vague to even parse. Who was eavesdropping on who? Both on each other? A mutually distrustful relationship? How much was the pay, what were the stipulations? Does 'duo' imply they work together?
Oh well, at least I know they're Asian.
