I think it was in his biography that he said he dreamed of working at Cadburys, a famous British chocolate company. I’m not 100% if he explicitly and directly connects that back to CatCF though.
tbh, reading it as a British kid, I saw and interpreted lots of allusions to American culture and I think it was intentional. He always seemed a bit of an America- and Anglo-phile, and I definitely saw that in his gun slinging kids and used car salesman father’s amongst others.
