I hate that 'When are you going to get a commercial licence?' question too. I usually reply never, I don't want to downgrade.
The cabin service question from burly blokes I respond with "Not unless you remembered to shave your legs this morning" or "You shave your legs, I'll supply the skirt". Sometimes I'll mention 'No cabin service' today because I forgot to shave my legs.
To "Is it safe?" I reply "Have you noticed I'm going to be flying in it too?"
