Answer:
No, a room attendant should not share information with others about a guest if he/she thinks what the guest is doing is morally wrong.
Step-by-step explanation:
Morality is a subjective issue. Even at that, what may be morally wrong can still be legal. Hence, there is no reason for a room attendant to share information with others about a guest if he/she thinks what the guest is doing is morally wrong.
For example, smoking shisha or drinking alcohol may be morally wrong to a room attendant, but it is legal for the guest to do in a guest house or hotel, hence the guest is within his rights to do so. Therefore, there is no need for a room attendant to inform others in as much it is legal.
