Awww, I'm sorry to hear that, but I COMPLETELY agree. We encountered more nasty, snarky, and rude cast members than ever before on our trip too. Unfortunately I ran into a lot of them when I worked there as well, and I just didn't get it.
I'm sure it is partly the transition, but I also think it's an attitude that's slowly seeping into the company culture. The Disney corporate mindset at the moment seems to be more and more about making money and tightening up restrictions often at the expense of the guest - you can only have this many fastpass+ or you can only have this many mug refills. And I feel like that corporate attitude of "If guests don't like it, tough" has been trickling down into some of the cast members. It's really sad.
