To be clear I mean these things but I have no control on the results of these sayings
  1. Safe drive
  2. Fly safe
  3. Tell so and so hi
  4. Have a good day
  5. Everything will work out
  6. You too.
    Is that a rude suggestion? It's, like, in the context of something like when your uber driver drops you off at JFK and says, "have a good flight." And you're mindlessly trying to find your drivers license and both of your iphones and say, "you too". Or any other scenario that's maybe completely different.
