Try Shaka brah!
It annoys me so much when i’m driving and theirs drivers that come into my lane and they don’t give me a thank you wave or worse…they don’t Shaka. Come on dude! A ‘thank you’ wave would be the courteous thing to do and a ‘Shaka’ would be the Aloha/Hawai’i thing to do. Lose money that kine.
Be safe ah.
