Exhibit one on your left
The statement, “Under no circumstances should you attempt to climb or fly,” is an example of a warning sign that businesses always revert to when someone sues them. In other words – the firm isn’t attempting to pull a fast one here. Hmph, at least it’s big, simple to read, and located in a spot where few people would miss it.
Nonetheless, this is a direct signal, getting right to the point. The sign may be criticized for being too theatrical, but at least it clarifies that random people should not walk behind the sign.
