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

"In Fort William, it's important to avoid referring to the locals as English, as Scotland has a distinct cultural identity separate from England. It's also considered disrespectful to mimic or mock the Scottish accent. Avoid making negative comments about Scottish food or drink, especially haggis and whisky, which are national symbols. It's also considered impolite to discuss religion or politics, particularly issues related to Scottish independence, unless the topic is brought up by someone else. When visiting any of the numerous historical sites or natural landmarks, be sure to respect the environment and follow any posted rules or guidelines. Lastly, while tipping is not as customary in Scotland as it is in some other countries, it's still appreciated for good service in restaurants and taxis," mentioned another expat when asked about moving to Fort William, Scotland.
