I was on the OP's cruise, and just to let you all know, I am really quite likely to down if there ever was an emergency
I heard the signal, and walked towards the restrooms where my wife was. She came out running, as were all the other passengers by now. She asked where her purse was, and I said, "dunno."
We rushed back to the bar to collect her purse, and on seeing my full drink, I asked whether she thought I should take it, "just in case."
Just in case what, I really don't know, but as a Brit I would guess, it means just in case I couldn't finish it!
At about this time, someone came on the tannoy to say it was a false alarm. There were very few people about - presumably already at their muster stations.
As I said, mostly likely to drown right here...
...But at least I would have finished my drink.
