why would you need to disable anything?
I once asked a hostie for a red wine. "since we are deviating to tullamarine can I get a red wine before you shut the shop?"
why do you think we are deviating?
I point at obvious course deviation on map track.
ok then.
comes back with the wine and says "you're right. you picked it even before we were told"
nice red btw. thanks qantas.
