I can assure you of this;
You will never see my wife or me operating a register in a checkout line.
Tattoos do not make people slow or less efficient, nor does being slow lead to tattoos.
Oh, my wife (and her Phd) have purple hair.
You are exactly what you accuse tattooed people of being. Slow and inefficient, only you exercise your inefficiency in bigotry.
My husband (and his PhD) has NO hair, blue or otherwise. LOL!
And, even after a career in Physics, and his TS and Q clearances, he has enough humility that he would have no problem operating a register in a checkout line. You do what you have to do sometimes. Snootiness doesn’t pay the bills.
I’m the opposite of slow and inefficient. I’m probably is bigot; everybody is bigoted in one way or another.
