:::TONE of VOICE::: & :::SAFETY FIRST:::
And finally, the TONE of your voice will determine how well your pax address is appreciated.
Some pax also enjoy being told (or so I hear) what kind of noises they can expect to hear during T/O and LDG (pax address before departure). Some older types make distinct noises when Gear/Flaps are moved.
But remember, SAFETY FIRST. i.e. rather make a good pax address before taxiing and then only once in cruise again and only after LDG when all "cockpit work" is done.
As you all know, runway incursions/taxyway incidents are on the rise. Rather say too little, but have all the situational awareness you can muster.
