re: Did Caine's sauce get smaller?

No. They are product testing some different brands of plastic cups, so you may have received one that is slightly differently shaped, thickness, etc. However they are still served as 2 oz portions.

Same amount of sauce in each cup I can assure you. (Unless they screwed up pumping it and didn't fill up the cups or something)

Now the size of the tenders have gotten smaller over the years. :(
