1. Do not hold your car keys and a bag of trash in the same hand as you walk to the Dumpster. 2. If you accidently toss your keys into said dumpster, do not climb in to get them. 3. If you are going to hop in, make sure you have a firm grasp on the stool you’ll need to climb back out again. 4. If you drop the stool on the outside of the dumpster, yelling for help will only get you a bunch of laughing co-workers with cell phone cameras.
