The drunken, violent Scot is a sterotype and one I only encountered once and that was in London when I was attacked by said stereotype after ejecting him from a bar. I arrested him and he got 6 months for assaulting a police officer. There are parts of London where it is dangerous to go and I suspect the same is true in most big cities, which is why whenever I've visited Scotland, I've avoided places like Glasgow.

Scotland has a thriving tourist industry and is a beautiful country. The people I encountered have been friendly and helpful, even though I had an English accent. The same can be said of the Scots I have met and know in Spain. The most hostile thing I ever encountered in Scotland was the midge! However when I visited Scotland I was unaware of my Welsh heritage and it was long before I began wearing a Welsh cilt. If I ever visited Scotland again, which sadly I can't imagine, I would wear my Welsh cilt, I would only wear my Powell of Wales cilt though, as it is so obviously not Scottish.

Living and working in London for 20 years, American tourists were common. They do not blend in well. They can often be heard long before they can be seen and in those days wore weird plaid trousers and the ubiquitous baseball cap. Draped in cameras with wives called Martha. Americans were looked on as gullable but generally harmless but kind of likeable like a puppy. However since those days due to international politics which can't be talked about, I think they aren't looked on in quite the same manner. I hope I'm wrong and it may be different in Scotland, I'm going on what it was like in London 10 years ago now, so I may well be out of date.
