I'm not picking a fight here, but you corrected a post from 'sweet tea' to 'sweet iced tea'. Technically, you are correct, but in the South, there is the phenomenon known as "Sweet Tea". To quote an outside source: "It's not iced tea, per se, at least as we know it. It's icy cold brewed tea -- served in a large glass or mug -- with double the normal amount of sugar, garnished with a mint sprig and lemon wedges.
As an example, I have friends who have hiked the Appalachian Trail from Georgia north .... one of the topics of conversation is how far north can you get "Sweet Tea" ... i.e. go into a restaurant and get the super sweet tea merely by asking for 'Sweet Tea' .... as opposed to the regular already-sweetened ice tea which most restaurants serve when you order iced tea & they ask "sweetened or unsweetened". :-)
If you're really a Southerner, you should know that it's "ice tea" -- no "d" after the ice!
