There was a guy who used to cut my grass and from time to time, he'd have his teenage daughter help him.
First time I saw here, she had on tennis shoes. I told dude that if he wanted here to help, she needes steel toe boots just like the ones he wore.
A few weeks later, I saw the daughter again with the same tennis shoes on.
I had to tell the guy I couldn't use him anymore as I could not stand to see the girl get hurt.
normally the OSHA approved tube top and cut-off shorts are enough
