Consume Product

It's bullshit: You can see in the video some woman carrying a handbag on the 2nd floor.

I suspect the climb is optional.

Also, this would be illegal because it endangers customers in case of fire and impedes firefighters.

The store could never exist because nobody would insure it and the council would immediately revoke the business license and close the store.

If the rock climb was voluntary and customers were required to sign away their rights to sue in case of injury, someone would eventually fall and sue them into bankruptcy by claiming the business failed to fulfill their legal health and safety obligations which can not be signed away.
