I was looking through the emojis in ios 10 recently trying to find one resembling a person tipping their hat, I was unsucsessful. I think it would be extremely smart for apple to add this emoji because it could be useful in many ways, complimenting somone, greeting somone, as a sign of 'gentlemanliness' via text and it could be used to congratulate somone. So join me in change and sign my petition, I would tip my hat but Apple hasnt added that emoji yet.
