Prompts, Prompts, Everywhere Prompts

Towel Prompt
I spend a lot of time in hotel rooms. And years ago hotels started putting a sign in the washroom like the one you see here. They are a good example of behaviour-changing prompts. Imagine all of the water and energy that has been saved because of these reminders.

It is ironic that nearby there are always those disposable little plastic shampoo bottles, though!
