The idea of the “ratches” in this comic actually comes from a restaurant I worked for many years ago (yes, I’ve been at a few.) They had some kind of infestation of massive proportions. So bad infact (among other horrible issues) the owners demolished the old building. I, along with many others, was hired to help fill in the gap left from the disbanded employees when the new, more modern building was done.
I don’t think I could actually tolerate working in a place overrun with some kind of pestilence. Bless any of you who may.
