When flight attendants do the safety dance and they are showing how to use the life vests, are those live/working vests?

No they are demo vests and as such inert. It goes for the battery and lights too. It is a legal requirement that a life vest is vacuum packed in a rip-able plastic bag. Each vest has a a unique serial number linked to date of manufacture, next servicing date and time-ex date. One of the reasons for it being sealed, it is a very quick way of knowing whether it is serviceable or not. Bag intact, serial number visible and expiry date good, all is OK.

1. Captain, if the problem is not entered into the technical logbook.........then the aircraft does not have a problem.
2. And, if you have time to write the fault on a napkin and attach to it to the yoke.........you have time to write it in the tech log....see point 1.
