Yo Gom,
I will quote one of our cousin's comment re GPS....."Never happen, give up going on about it....after all it is an American DOD thing!"
Then.....the Nigerian CAA made it a requirement.
The next comment was...."Well when they go U/S (unserviceable)....we will not repair or replace them!"
The major thing was not to disturb his serviette...as he got very cross.
