You have to keep professional conduct at all times.
Follow the principles of professionalism. That means:
Responsibility, Integrity, Respect, and Ethics!
Act according to what you are expected to. e.g., When working at a museum, never allow people to cross barriers or touch an exhibiting artwork.
➜ Respect: Show respect for both customers and co-workers.
e.g., Address customers as Mr or Mrs and make sure to smile and treat them nicely, especially if you have to call their attention to something they are not allowed to do.
➜ Ethics: Do not take advantage of situations. Know what is right and wrong and always choose what is right.
e.g., If carrots are dangled, don't take them. Act according to what you are professionally expected to.
