We Don't Have an STD

I'm one of the owners of a trucking company that's called STD.
Nobody will hire us, even when we offered to work for free.
The STD stands for Simpson, Taylor and Drees.
But people think it stands for Sexually transmitted disease.
My partners suggested that we rename our company to DTS or TDS.
But I'm Simpson and I founded the company, so I refused to say yes.
You don't see any of our trucks on the road because people are afraid of us.
They think we have Aids or Herpes and it causes a lot of anger and disgust.
We don't have an STD, so please hire us, I'm so desperate that I'm willing to crawl.
If you don't hire us, I'll personally come to your house and kick you in the balls.
