Ah, I get it. Okay, that's fair enough. I am actually quite pleased to know that if I order sweet tea in England, I'll get hot, sweet tea with milk in it. Who knew?! (Besides British people, naturally.)
If you asked for sweet tea here (American South, primarily, though some blessed locations outside of the South serve it as well), you'd get a glass of cold tea, probably with ice in it, that is so sweet it makes your teeth ache. (Important Edit: there would be no milk or cream in it, either.)
If I recall (and I may not!), the original discussion from whence the comment came was comparing the phrase "iced tea" with "ice tea," itself a comparison for "waxed paper" vs. "wax paper."
