Clean Up After Yourself, Then
It is always a nice thing to do to show your appreciation to people that look after the workplace. Custodians are often underappreciated even though they work very hard to keep the properties where they work in tip-top shape. A little token of appreciation can go a long way, especially from the people that work above you.

Whoever wrote this note has obviously never had to clean a day in their life. Custodians are often the backbone of many workplaces and definitely deserve our recognition. We don’t find this very funny, and neither will the person who wrote this sign when they find out what the custodian did with their phone.
