As an acupuncturist, I have to convince some of my patients that the needles we use aren't dirty even though they are.
Why would you lie and use dirty needles?
I use my professional skills to manipulate some patients to my side.
It is wrong to lie to people and trick them into using dirty needles. They could catch something and become sick.
It's their choice if they use the needle.
It's not a choice if you lie to them that it's dirty. Think about how it could ruin your business if patients get sick and find out what you have been doing.
