A joke plot about retail hell.
You are a clerk at a certain supermarket. However, this supermarket is a breeding ground for complainers and nuisance customers. Today, yet another new customer has arrived. Honestly, the customer isn't always God.
A troublesome customer who makes various complaints. Diverse in age and gender! Sometimes, they might not even be human...?
"Why am I the one apologizing...?"
That is a feeling every retail worker in the country has likely felt at least once.
Unreasonable demands, endless complaints, bulk purchases at closing time, cart armies blocking the aisles—.
In the retail industry, various "nuisance customers" appear today as well.
This book is a slightly funny, slightly relatable field guide summarizing the characteristics and ecology of the nuisance customers who plague these clerks.
How many types of customers have you encountered?
Now, restock your mental inventory and turn the page.
—Customer service is a survival game, even today.
