When visiting Pondicherry, it's important to dress modestly, especially when visiting temples and religious sites. It's customary to remove your footwear before entering someone's home or a place of worship. Tipping is not as common in India as in Western countries; however, rounding up the bill or offering a small tip for exceptional service is appreciated. When interacting with locals, it's polite to address them with respect using titles such as 'Sir' or 'Madam', and always seek permission before taking photographs of people or their property.
