What cultural faux pas should I try to avoid making in Sentosa Cove?

"In Sentosa Cove, it's important to avoid littering as Singapore has strict laws against it. Chewing gum is also banned in Singapore, so avoid bringing it into the country. When using public transportation or entering buildings, avoid eating or drinking as it's generally frowned upon. It's also important to respect the diverse cultures and religions in Singapore. Avoid making insensitive comments or jokes about race, religion, or nationality. When visiting religious sites, dress modestly and follow the rules of the site. For example, remove your shoes before entering a mosque or a Hindu temple. In conversation, avoid discussing politics or criticizing the government. Singaporeans value harmony and avoid confrontational topics. Lastly, tipping is not customary in Singapore. Service charge is usually included in the bill, so there's no need to leave extra money," remarked another expat in Sentosa Cove, Singapore.
