🌟 Hit me up — Write me 🌟 Catch up — See you later 🌟 It's on me — I'll pay for it 🌟 (It's) On the house — Our restaurant will pay for it 🌟 Sleep on it — Think about it (properly) 🌟 Not my cup of tea — I'm not interested 🌟 Break a leg — Good luck 🌟 Beats me — I have no idea 🌟 Play it by ear — Go with the flow 🌟 Not in my books — I disagree 🌟 Take it easy — Bye for now
