Idea behind this is that megumi comes out whenever yuuji is in conflict (with himself, with a curse, with someone, whatever situation) and the worse his stress the more megumis there are. Yuuji can understand him but sometimes curse megumi is unintelligible, sometimes he speaks completely clearly, though the more of him there are (aka the more stressed he is) its harder to make out what hes saying, so he tries to stay mellow

In this instance, yuuji isn't all that stressed but he's in "conflict" enough that one megumi is summoned. Yuuji is genuinely wondering if he shouldve ordered extra spicy. The funny (and kinda not funny) thing about this curse is that it doesnt differentiate the seriousness of the situation. So Yuuji kinda takes advantage of it, uses those not so serious times to talk to megumi as if he were alive, and megumi responds as he would. But he doesnt always recall their previous encounters. You can imagine how this can be frustrating so yuuji keeps conversations light and "meaningless" to save them both the grief.

I would like to draw more of when ghere are multiple megumis too because its kind of a feedback loop of yuuji is stressed -> multiple megumis show up -> theyre hard to understand so he cant communicate with megumi -> he gets more stressed out -> more megumis show up, so he has to cope veryyy well to avoid this spiral.
