Or it is type I diabetes and you're an asshole.

he's from france you ******* how is no-one getting this?

Imagine that, a narrow minded person not caring about any evidence proving them wrong. Hmmmmm.

FYL OP, that really sucks. Talk to the manager about emphasizing getting the order right. At the place I used to work at this one lady ordered a tea in the drivethrough, but then came back SCREAMING like 15 minutes later 'cause we "gave her sweet tea and she's a diabetic and was gonna sue us because we tried to POISON her." Now, she was full of shit because we didn't HAVE sweet tea, we didn't start selling it until a month or so afterward, but the manager made sure to emphasize that we ask to make sure we have the right order and then double checking it before we hand it out. As for all the "YDI" idiots, **** off. Some people can't tell the taste difference between diet soda and regular, I'm one of them. The only way I can tell is to have someone sip it for me first, or by the massive ******* migraine I get half an hour or so after drinking that shit. Which is why i usually just order juice anyways.

OMG thats horable. F-U to the pplz who said u deserved it. and what fast food places make u fill ur own drink?

Total crap. I'm an insulin-dependant Diabetic and after the first sip I can tell if it's diet or not.

law suit

All you people are saying he/she deserves it but because they should be trained and all that.But how do you know how long they've been a diabetic? And even if he he/she has been one for a while not all people can taste the difference between regular and diet sodas. Just because you can doesn't mean that they can too. And why do people seem to think that EVERYTHING at fast food restaurants is full of carbs and sugar? Nobody deserves for this to happen to them because they can die from it. If this happened to you,you would be mad too.

Oy, oy, the misconceptions about diabetes. As a type I diabetic, I can say the following things: 1) Most (type I, at least, since everybody seems to think in terms of type II, which unlike type I can be treated with diet, these days) diabetics can eat whatever the hell they want as long as they give adequate amounts of insulin. I've been diabetic for over 8 years and fast food has never given me problems so long as I accurately calculate the carb count. (and if the fat content does cause problems, like sometimes for with pizza, you just alter the amount or the way you bolus the insulin) 2) My diabetes has always been fairly well-controlled, but brittle or not a spike in BG is neither cause for OMG HOSPITAL alarm (unless it lasts for more than a few hours and shifts into keto, which I have no experience with admittedly, but it'd take a lot more than a regular soda to do that) nor a lawsuit. It just sucks like HELL - sitting there for a few hours feeling thirsty, having a strong headache, and wanting to throw up. And soda raises your BG FAST. By the time you're testing your BG again it's probably already kicked in (and I'm often thirsty no matter how much I've drank after eating salty fries, and since that's pretty much the earliest sign of high BG I can understand not noticing it). So the OP doesn't necessarily have bad control. As for mistaking regular soda for diet...definitely possible, especially with fountain soda. The watery flavor of that type of soda can make the difference in sweetness rather subtle, and more than once I have accidentally taken a sip of a friend's fountain regular soda and not noticed the difference until they took a sip of my diet and wanted a switch. Unless my BG is low (when everything magically seems to taste more flavorful) I'm usually too busy eating to notice the difference. In short...FYL. Hope you're feeling better.

How can you not tell whether it's diet or not? YDI for not being able to tell something so damn easy.
