Last spring I was in the bathroom at a movie theater at 10:13 pm and saw this in the bathroom in plain view. Typically trash negligence is not time stamped, note the 11am time printed on the ticket. 10 hours is too long for trash to stay in one place at your business.
A big peeve of mine is any type of business that does not clean the bathrooms regularly or throughly. I once read that at Charlie Trotter’s an employee of any level was expected to check the rest room after each guest. Now you might not be running a Michelin rated restaurant but an exceedingly simple way to ensure your customers feel taken care of is to keep your bathrooms nice and clean.
