When visiting Tiruchirappalli, it's important to remember a few cultural norms and etiquettes. Respect for elders is highly valued, so it's customary to greet them with a 'Namaste' and seek their blessings. Dress modestly when visiting religious sites, covering shoulders and legs. Tipping is not mandatory as it is not a common practice, but is appreciated for exceptional service. When dining, it's customary to wash your hands before and after the meal. Embracing these local customs will help ensure a respectful and enjoyable visit.
