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

"In Southport, it's important to respect the local customs and traditions. Avoid making negative comments about the monarchy or the British government, as this can be seen as disrespectful. Don't jump queues or push in line, as this is considered very rude in British culture. Avoid discussing sensitive topics such as religion and politics unless you know the person well. It's also considered impolite to ask personal questions about someone's income, age, or marital status. In the UK, tipping is customary but not mandatory. However, it's considered polite to leave a tip of around 10-15% in restaurants. Avoid talking loudly in public places, as this can be seen as disruptive and disrespectful. Lastly, remember to say "please" and "thank you" as British people place a high value on politeness," remarked another expat in Southport, England.
