Tea Vs. Sweet Tea

So I love McDonalds tea, it is one of my very favorite drinks. I don't do tea that isn't fresh brewed and since I am from the south I am familiar with tea and sweet tea. In TX there are two things you should know about drinks. 1. Everything is Coke. At a restaurant if you say I'll have a coke don't be surprised when they say what kind? This is where you respond Dr. Pepper, Diet Coke, Orange or whatever soft drink you were wanting. 2. If you order tea they will ask regular or sweet, most establishments from Whataburger (one of my first destinations when I get to TX) to fancy restaurants will have 2 pitchers one for regular tea and one for sweet tea. Sure you could put the sugar in yourself but it is so popular they do it for you. I personally don't care for sweet tea, it is just, well too sweet. Now if you are here in Michigan you have noticed that Mickey D's has rolled out there new sweet tea campaign. So here is my beef (no pun intended) with the campaign. You can order a large sweet tea for 1.00 or get a plain ol large tea for 1.69? WHY in the world would you need to charge .69 more for tea that doesn't have the added sugar or whatever they use to make it sweet? In a world that makes sense wouldn't you think you could argue that the sweet tea would be more expensive due to the added expense necessary in the sweetener? I don't know maybe I am just disappointed with service issues all around, what do you think?
