Thank you for the chapter, as usual! This chapter gave me some insights of the strict standards the Japanese had, that's for sure. 😅
By the way, I studied in Japan for a while, and we (me and my friends) did a food stall twice or thrice, in my university annual fest and in a small international fest (?), yet I don't remember doing the same thing this comic describes or had a health inspector visiting us. I studied in Hokkaido 🤔 so maybe this stool inspection thingie is prefecture based? No idea tho 🤔
