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 behaviour matters most when the going gets tough.
That’s why McDonald’s systems ensure that bathrooms are cleaned every 15 minutes (I’ve done the cleaning…). Bathrooms matter. A lot.
So, how much attention do you pay to the bathrooms where you live and work?
