the final straw was a scene where a female player worried about his class tries to advise/warn him about the difficulty in being a chef. She does this very respectfully and accepts when she realizes hes just in it for the food and leaves.

she is then contacted by a superior and asked to send a messa To the MC about a contract offer. She tries to call out to him but since hes eating he ignores her. She then stutteringly touches his shoulder and he goes ballistic threatening to stab her. She runs off afraid cuz of the killing intent he blasted her.

Really after that I couldn’t really buy into the lie that he was a good guy. I mean the girl did nothing to him and we later learn he was pissed off because it was discussing money and him being the Son of a rich CEO he disdains such “things”. I gotta say that the MC lost all my respect after that.

People going off about the MC's bad personality... where?

I don't find him to be unreasonable. He's not doing anything overboard like lying, cheating, stealing, etc. He treats people courteously and isn't racist or sexist or whatever. He's actually quite a bland character. The only instances of him behaving out of social norms is when food is involved, and this is his most prominent (perhaps only) flaw. And I don't feel that this flaw detracts from his overall appeal. Bland though he is, I wouldn't call him unlikeable.

For example, chapters 34-35-36 heavily feature a female character who randomly decides to foist unsolicited advice on MC to the tune of "you should quit your class because it's hard to level up" and MC disregards her.

Uh, yeah? I would too! Why is this considered a bad thing? What should he do? Cry and delete his character? Kneel and thank her for her profound wisdom? Everyone has their own way of playing! Should everyone just follow walkthroughs and play the "right" way or the "efficient" way? It's very highhanded for someone approach a complete stranger to offer unwanted advice like this.

Next chapter, same female approaches MC while he is eating, (bad move) and tries to recruit him for some famous chef guy. (Later, it is revealed that the famous chef had ill intentions, but that's not really the point. Anyway--) MC ignores her. She's a stranger. He's busy and he's hungry.

She touches touches his shoulder to get his attention. He freaks out, knives out.

Yes, his reaction is over the top, yes, he's borderline psychotic, (it has been established that he has mental issues.) But can you really blame him for reacting like he did, mental illness or not?

What should he have done? She's a stranger, he doesn't owe her anything, and she has proven to be a rude person that doesn't respect personal boundaries. Think about it. If you were eating in a restaurant, how would you feel if a complete stranger came up to you, randomly solicited you for a third party and then TOUCHED YOU after you expressed that you didn't want to talk to them? I don't know about you, but I wouldn't be happy.

Not to mention MC is like a mean dog with a bone when he's eating. Never bother a dog when it's eating.

If the girl had a trace of politeness in her, instead of the entitled "how dare he show no interest in me the very nerve" mindset she has, it could have gone down differently. Hell, she could have just waited until he was finished eating to talk to him. But nooo.

Next chapter, MC explains why he's not interested in the offer. Basically, MC is rich and uh... the other party didn't show him a modicum of respect by throwing money at him.

If the famous chef person truly valued MC, he would have appeared in person to introduce himself and then make an offer after getting acquainted with MC. They way MC was approached shows that the other party simply doesn't care about him and is only interested in exploiting him. Why should he treat the messenger gently?
