The class of a place is directly linked to the class of the bathroom. You’ll never find a 5 star hotel with pathetic bathrooms.
So, the next time, you are at a nice looking store/house/office with pathetic bathrooms, the “nice looks” are likely to be just a front. It’s just like the fact that your behavior matters most when the going gets tough.
That’s why McDonald’s systems ensure that bathrooms are cleaned every 15 minutes. Bathrooms matter. A lot.
So, how much attention do you pay to the bathrooms where you live and work?
