People seem to think I am weird for carrying around Diastix. Sometimes even people who later ask to use them. Well, they're cheaper than test strips for testing drinks.
Lately I've been having bad luck with drinks. I went to dinner with my housemate at a new restaurant and we both got diet RC. His was diet and mine was regular. Huh? The waiter said he pressed the same button, so we concluded it was the machine (although you kind of have to say that or people get offended). In fact, he got pretty agitated anyway (he kept insisting it *was* diet, up until I showed him the strip). I don't really get what happened, but I guess sometimes when it runs out it can switch over to another tank? He got us some water and then never came back to our table. Now I have to wonder if he got so worked up because they ran out of diet and he thought we wouldn't notice.
Then we were having dinner at a large chain restaurant and we both ordered diet Sprite. We both got regular. The waiter said he'd have them check the machine and then came back with some diet. No need to get all upset, heh.
A couple days ago we went to see a movie. I got a large diet Coke (aren't they all large?). Our housemate watched them pour it, so he knew it came out of the "diet" dispenser. I tested it and got inconclusive results, so I tested it with my meter (as control solution, of course) and got 150. Diet is "error" and regular is 500-700. I drank it anyway, but bolused for 10g. It seemed to be okay.
The oddest thing is that even though I can always tell regular from diet, in all those cases it was unclear to me because the mix was pretty off. Sometimes fountain drinks can taste really odd. Still, I've sure learned to trust that nagging feeling!
