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

"When visiting Manchester, avoid making the following cultural faux pas: 1. Refrain from talking loudly or being overly boisterous in public spaces, as this may be seen as rude or disrespectful. 2. Do not jump queues or push your way through crowds, as this is considered impolite. 3. Avoid discussing sensitive topics such as politics, religion, or Brexit, unless you are well-informed and can engage in a respectful conversation. 4. Do not refer to the entire United Kingdom as "England," as this can be offensive to people from Scotland, Wales, and Northern Ireland. 5. Be mindful of personal space and avoid touching people you do not know well. 6. Do not assume everyone in Manchester is a fan of Manchester United or Manchester City football clubs, as there are many different football allegiances in the city. 7. Avoid making negative comments about the weather, as this is a common stereotype about the UK and may be seen as unoriginal or tiresome. 8. Do not make derogatory comments about the local accent or dialect, as this can be offensive to residents. 9. Be punctual for appointments and meetings, as being late is considered disrespectful. 10. When dining out, do not snap your fingers or wave your arms to get the attention of waitstaff, as this is considered rude. Instead, make eye contact and raise your hand slightly," said another expat in Manchester, England.
