Yeah, but he is also very drunk and uninhibited by that point because his boss keeps pushing scotches on him. He also goes to save his life without hesitation too. So not great, but again, could have been much worse.

Edit: I just thought about it and, if I remember correctly, he is not present when Stu orders and says he’s very allergic. They decide to order while waiting for Mrs. Doubtfire who had been “in the bathroom” for a long time. So he didn’t know Stu was allergic. Daniel just hears the cook call out the “non-spicy” dish for their table in the kitchen and then adds cayenne to it to fuck with him. Petty for sure, but he didn’t intend to seriously hurt the guy.
