What bothers me about this is that people are going to make this a trend. At my job, we've already had 3 people do this. The first time was kind of funny to see. Anything else? No. Not to mention the people trying to pass it off as a real fall so it turns from a prank into some weird legal issues.
I realize it's part of our job description to clean up spills, but it kind of sucks when we can't save a box of cereal because the dip who broke the gallon got it all over the box. Not to mention that we're only there for 4 - 5 hours. If we have to keep taking out of our shift to clean up spill after spill, we can't get anything done.
