I once took a flight that was operated by LatCharter, cannot remember who the flight was for but it was a UK leisure tour operator.
The only announcements from the captain (or First Officer, I honestly could not tell) were the "cabin crew seats" at take off and landing.
All I heard was static and the cabin crew seemed to take an awfully long time to realise what the pilots were probably saying, surely it is a requirement to have some clarity in the pilots' PA microphones?
