Spot on MA and don't forget the spreading of cold and flu bugs during the winter. I wonder how many extra sick days are taken as a direct result.
I believe the anticeptic wipe is a waste of time and does not thoroughly clean the headset.
Imagine if all the passenger headsets were just left in the seatpockets for the next customer, would that be acceptable?
What would be the cost of an personal headset per flight over say 2 years, probably about 50p.
