This is common sense in this world, if you are going to offer an apology, at least give some benefits or you will prove that you are not sincere. Conrad only wanted to mitigate the problem, spending as little as he could and that was why he had not offered anything.
This showed how insincere he was and Andrew was ignorant of this. To him the problem that Conrad caused was not something to take into account, so he did not plan to make things difficult for him, but now that Gaston intervened, he noticed Conrad's lack of respect.
Conrad being thick-skinned as he was, immediately smiled feigning embarrassment, and quickly said, "Of course, I brought an apology gift," and without waiting for anyone to say anything, he took out several boxes of firebird eggs from his dimensional bag.
