Avoid discussing politics, religion, or other controversial topics in casual conversations, as it may make people uncomfortable. 3. Do not make offensive jokes or use derogatory language, as it may be considered disrespectful and impolite. 4. Refrain from speaking loudly or drawing unnecessary attention to yourself in public spaces, as it may be seen as disruptive and rude. 5. Do not litter or leave trash behind, as cleanliness and environmental responsibility are important values in the UK. 6. Avoid using your mobile phone or electronic devices during social interactions, as it may be perceived as rude and disrespectful. 7. Do not assume that everyone in Eastbourne is from London or has a strong British accent, as the UK is a diverse country with various regional accents and backgrounds. 8.
