unsure abou how often; I don't do it because I have to meet a quota, it's more of a I-can't-hold-to-myself-when-I'm-✨bedazzled✨ kinda thing?

Although as others have mentioned, I don't wanna sound creepy; for strangers it's generally about a cool accessory they're wearing. i verbalize the compliment by refering to their uniqueness, not intending to start a conversation just, "cool hat 👍"

interesting question, thanks!
