Went through drive thru ordered Medium Iced Cap. Immediately after I left it began to separate. I stirred it tasted it & it was a little sour and very strong on the coffee. I tried tasting it hoping it would taste different as I continued to stir and it continued to separate. Within 10 minutes it was totally separated and very dark. This has only happened to me once before, I love iced caps please try to get to the bottom of this problem which occurs rarely. Thanks
