So a Chinese guy just came in the shop.
It's not important to the story that he was Chinese.
Here is the conversation:
CHINESE GUY: "Do you have any plastic snakes or rubber rats?"
ME: "I don't have any plastic snakes but I do have this one rubber rat."
:::shows him rubber rat:::
CHINESE GUY: "No, that won't do. It's too big."
The rubber rat was the size of a real rat.
