It's not even my original idea, back when I was working at a grocery store, one of our butchers got mad at a Karen demanding bacon when they were sold out, and he screamed " I CAN'T SHIT YOU BACON, MA'AM!!!!" So I got to use it at this job! lol
Seems like a measured, rational response given the situation. :)
I think you channeled your inner Toriyama on that second panel! If the Mario comic doesn't work out, there's a gig in shounen manga for you.
