Haven't seen this topic here before. 'High Tea' seems to go wrong whenever it leaves England. In Holland High tea is also misunderstood. Is associated with the 3 tier trays that I see used for Afternoon Tea and hardly anyone knows High Tea means the evening meal.
I never knew the heights of the table played a distinctive part in this. Good for a reminder! smile

I bet there are many borrowed word in all languages that are used in a correct incorrect way.
