Using the wrong register is a form of humor as well just like in English and other languages but with different impact due to the politeness level being so important to the syntactic structure just like in Japanese. Being overly polite or using too low of a register works much better than sarcasm for comedic purposes for reasons I can’t quite explain. In English sarcasm is commonly how I joke around and involves an intonation cue but it doesn’t really work in Korean even with intonation (possibly because intonation and vowel lengthening is used for a lot of word distinction perhaps although homonyms exist in basically all languages) and if you try it native speakers will oftentimes have trouble telling if you’re serious or not. Although these days due to Western influences IMO most Koreans understand sarcasm as a style of humor and can apply it for all languages although for older generations it’s going to be less natural. The country’s had massive, massive social and economic changes in the past 100 years, it’s kind of wild

There are many levels of honorifics, from very low form to very polite form. Most aren’t used on a daily basis though, just like how most people don’t speak like they’re a lawyer addressing a courtroom.

I tried translating it with a tool:

"존경하는 각하, 맥주 한 잔만 드시게 해달라고 겸손히 부탁드려도 될까요?"

Does that sound about right?

Close. But 드시게 is not correct in that place because its an honorific form given to yourself when you're trying to honor the other person. And I'd rather use 감히 instead of 겸손히, which can be roughly translated into "dare to"

"존경하는 각하, 맥주 한 잔만 마시게 해달라고 감히 부탁드려도 될까요?"

Another Korean here. Usually in Korea, one could refer to an unknown someone as "선생님(teacher)". "각하", on the other hand, has been referred to the President of Korea. So it really sounds weird to a Korean. When someone calls you "각하". If I were to be a customer, then I would be called "고객님". Where "고객" means customer and "님" is like "sama" in Japanese, and "sir" in English.

Formality and politeness is baked into Korean and you are basically always speaking at the right formality unless you ignore the rules.

Your relationship to who you're speaking to (and who you are referring to if you speak about anyone else) changes the grammar of the sentence.

The grammar changes mostly manifest in different suffix endings.

How do noble or formal titles work then?

It seems very unlikely to just be a suffix ending.

The rules for how you speak to people and how you address people you are speaking about are different.

The whole thing is a bit more complex than suffix changes alone especially with more out there titles but generally speaking,

I think you've seen a bit on how the endings would change depending on your relationship to the hearer.

For the latter(addressing people you're speaking about) You would basically never call an acquaintance just by name

For instance, take the name 김영철

If you were on relatively equal social standing, you would generally address 김영철 as 김영철 씨 or 영철 씨

If you wanted to take it a step further in respect, you would replace 씨 with 님

For a senior in age or experience in say the workplace, it would become 선배 but this can be used on its without the name attached.

There are also different words for how you would address different members of the family. Unlike in English, you would basically never call an older brother or sister by their actual name. It's more a generic brother or sister word that changes depending on if the speaker is male or female.

For royalty, there'll be surgery trends for different members of the royalty.

Forgot to mention. The brother/sister words don't necessarily need to be referring to an actual brother or sister.

They can be used endearingly to refer to older males/females you are close to.

오빠 can be used somewhat flirtingly/romantically as well
