What to say when leaving a cafe in Korea

1. 수고하세요!

• 수고하다 = to work hard (do hard work)
• ...하세요 = Do ...

It's like saying "Keep up the good work!"

Technically speaking, you should not use '수고하다' to higher-ups, but no-one will be offended if you use it when exiting a restaurant (식당), cafe (카페), or convenience store (편의점)!

2. 감사합니다.

"Thank you!" - quick and easy!

3. 안녕히 계세요.

• 안녕히 = peacefully
• 계시다 = to stay (formal)

"Goodbye" - this is another common phrase you can use!

4. 또 올게요!

• 또 = Again
• 오다 = to come

"I'll be back!" - If you really like a place so much that you decide to become a regular, let the owners know you'll be back with this phrase!
