I went to the park recently, and observed a great example of offering a clear choice.

The toilet had a cubicle with no door (I think it was temporarily gone).

That cubicle was presenting a clear choice: “If you want to use me, people are going to be able to see you. If you don’t want that, find another cubicle with a door.”

"I am this thing offering this service - if you want that service, go elsewhere.”

I think more businesses could benefit from offering clear choices like this.
