They don't allow sandals on the course where I work. They claim it's to eliminate chemical exposure. I don't buy that because they don't have a rule against licking your balls.
The first time we played there my wife had a brand new pair of sandal golf shoes. On the way to the course she said she couldn't wait to play in her new shoes.
When they told her she couldn't go on the course with them I never felt more sorry for her in my life.
I work there now and I still think it's a BS rule but nothing I can do about it.
That's pretty weird. I'm sure your course would enjoy trailer trash like me spitting chew into the rough out of the side of my cart.
