Hotel restrooms are the fanciest – always use them
If you are out and about and have to go to the restroom, find a fancy hotel and use that restroom. Chances are, it will be better than any public restroom that is accessible because hotels have a reputation to uphold as well as a customer base to satisfy.
They cannot let things slip or go off the rails because it would not be good for business. Find these restrooms and do your business in luxury, it is worth it. It will take you away from reality for a brief moment, and you can recharge yourself without even staying in that fancy hotel.
