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

"In Dundee, it's important to avoid making negative comments about the Scottish accent or dialect, as it's a significant part of their cultural identity. It's also considered rude to interrupt someone while they're speaking, so always wait for your turn to talk. Avoid discussing sensitive topics like religion and politics unless you're familiar with the person you're talking to. Scottish people are proud of their heritage, so don't make derogatory comments about Scotland or compare it unfavorably to other countries. It's also considered impolite to refuse an offer of food or drink, especially in someone's home. If you're invited to a pub, it's customary to buy a round of drinks for everyone in your group. Don't assume that everyone in Scotland supports independence; it's a divisive issue and not everyone holds the same opinion. Lastly, avoid referring to Scotland as England or part of England, as this is a common mistake that can cause offense," remarked another expat in Dundee, Scotland.
