A new low

Can't ask them to stop, cus they will simply Dublin down the pun
- Pun 10/10, execution 6/10
  “You can’t even ask them to drop the puns—their response will just be Dublin down”
  
  For the uninitiated, what does Dublin have to do with chickens? I searched but I just got restaurants from Ireland.

Funny meta social media posts? Fine. Whatever.
But this is honestly just insulting and unprofessional.
I’m sure they get some applications from people who genuinely need that job, and then they’d get sent that rejection…
- It has bad management decision written all over it. Some idiot in the hierarchy thinks they are being cute and ‘relatable’ in their own words I’m sure.

Did they just tell you that you're not good enough to put chicken in bucket?
- KFC is franchised and there are lots of corporate roles. Could be one of those.
  
  Guarantee that's what this is for. No restaurant manager would bother denying with outright denying an application, yet alone sending a rejection email.
- It may be a lack of spatial awareness. They use commercial pressure cookers. If you aren't careful with those things you can blow up the kitchen.

If I got something like this after applying to a fast food place there's a non-zero chance I kill myself.
Wtf do you mean I don't have the skills? What skills?
- KFC in particular uses commercial pressure cookers, or at least they originally did I haven't worked there since before they were called KFC. Those things are dangerous, and if you didn't appear to have a decent amount of spatial awareness, I wouldn't hire you at my store, cause an accident with one of those pressure cookers could end in an explosion.
  
  Things might have changed since the 90s, however I worked at multiple KFCs and the intelligence level of the people they hired to run these things was pretty damn low. In fact, at one store most of the cooks were stoned every single shift. Nobody got seriously hurt.

That's not how a professional company rejects an applicant. Judging by this grammarless email (and this email alone), it sounds like you may have dodged a bullet. I am sorry that you've been rejected, though. That's never a fun experience, and their lack of compassion in their "cute" (but actually rather insulting) email is incomprehensible. Just because they didn't see you a a secret recipe, doesn't mean you're not. KFC has gone down hill more than almost any other chain in terms of flavor and quality, and their email here is a testament to their decision-making skills they seem to still be lacking.
E: autocorrect and my own mistakes.
- Also, KFC continues to work in Russia, sponsoring the war through taxes. Just in case anyone needs more reasons to hate them
- KFC USA always sucked. They have much more variety and quality in other countries. Speaking from experience.
