OMG - I was a few feet away when it happened. I heard all the commotion and then a woman appeared {a passenger} telling everyone to get off, when I asked why she said that, she responded that her beer bottle dropped and shattered the glass walkway.
She added since it was it was her fault, she was helping staff to get every one get away, acting so proud she had shattered the glass. Lovely, for a sail away party where everyone was enjoying the views and excellent weather and thrown off.
I asked her how she could have possibly brought up a glass bottle since all the pool deck drinks are served in plastic and she admitted she brought it from another deck.
As a result the whole walkway was closed for the entire cruise.
It's people like this that ruin it for the rest of us.
