Bangkok Business Pulse
- Culture Respectful and hierarchical. The "Sanuk" principle (fun) means keeping a positive and calm atmosphere.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Call between 10:00 AM and 11:30 AM or 2:00 PM and 4:30 PM. Always maintain a calm, polite tone ("Jai Yen"). Showing anger or impatience ("Jai Rorn") will lead to a loss of respect. Use the "Wai" (traditional greeting) if on video, and always address people with the polite title "Khun".
San Francisco Business Pulse
- Culture Innovation-focused and casual. Values disruption, speed, and technical excellence.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Best reached between 10:00 AM and 4:00 PM. Expect a casual, tech-first vibe—informal language and dress are the norm. However, technical competence and speed are non-negotiable. Many in the Bay Area work non-traditional hours, but standard business times remain the safest bet.
