Useful starting points
Dress and formality should reflect the setting and host expectations.
Be attentive to Ramadan and religious observance when scheduling or hosting.
Public-sector and high-level engagements may require more formal protocol preparation.
Culture is context, not a script.
Individual preference, profession, generation, region, language, organisation and the specific relationship may matter as much as nationality. Observe, ask respectfully and follow the host organisation’s guidance for formal situations.
