I've lived in many places around Europe, and I've lived among Americans from all over the US, and I definitely noticed a difference. Perhaps you're right about cocktails, but in most cases American used ice where the Europeans didn't (a glass of coke being a prime example). They would even did this in winter, which always seemed funny to 'us' Europeans.
