Answer:
Although it sounds like I work on a transportation device I actually work in a restaurant.
I am asleep when you are awake I am awake when you fall asleep. I can fly but no feathers to aid my flight.
I stay where I am when I go off. What am I?
While you were folding a letter you got me. Usually you will do whatever it takes to avoid me but now you can't help but find me.
I wonβt break if you throw me off from the highest building but I will break if you place me in the ocean.
The warmer I am the fresher I am.
