"...the crew seemed very unprofessional"
If I was on a ship listing badly by the second, the only thing that would make sense to me would be self preservation, that's not out of selfishness, what else can you do if every thing's sliding dangerously to one side, tables, chairs, bottles, people. Calming but professional palm court quintets would be the last thing that would interest me right then.
The Titanic was unusual in that it had time for everyone to board a life boat had there been enough, but most passenger ship disasters since have happened within minutes. The RORO ferries being the quickest having huge areas low down with no stabilising bulkheads that can cause a ship to capsize in the time it takes only a few inches of water to rush to one side.
