Won't buy anymore

It might just be me, but I find the Big Crunch is not so big anymore. I feel that KFC has changed their portion sizes, or perhaps it's the location we go to. This used to be my go to item along with fries and a drink, but the last two times I have ordered it, I get a ton of bun - with a small piece of breaded chicken, and little mayo. The chicken itself hasn't changed and is as delicious as ever, but I kinda want a piece that is kinda comparable to the size of the bun and for this reason, I don't order this off their menu anymore. I would have rated it even lower, but the chicken is yummy.

Why?

I don't understand how people eat KFC chicken and it feel sick to their stomach . I had Big Crunch and I had a really bad after taste , and I gave half away to my sister
