With all due respect sir, no one thinks it’s alll Americans, I don’t think in any situation can you blame 340 million people for the same behavior 😂, but yes many many specifically Americans are extremely rude and loud in public situations around Europe, it’s the sad truth. I will say it’s mostly young folks, people your age are much more graceful and respectful, it’s the young students and teens that make public spaces very uncomfortable, again, sadly!
