News flash: bottles break easily
Never stand on top of glass bottles unless you want to run the risk of cutting up your legs and feet really badly. That should be common sense knowledge, but this guy didn't get that memo.
Whether he's an employee trying to rearrange things or a customer trying to reach the bottles he wants, it doesn't even matter. It's still a really stupid move, and we can't believe it. Instead of pointing that out to him, this person snapped a picture.
