William was leisurely reading a book, but from time to time, a few customers would still come into the store.
Bookstores are different from bars. When customers come in, there's no need to greet them. Most people browsing in bookstores are students. They find the books they want on the shelves by themselves, and usually only need assistance when checking out.
On the ground floor of the store, there was a large table. But when Alice and her friends ordered fried fish sticks, the aromatic scent wafted everywhere. To prevent it from being unsightly to the incoming customers, they took their food upstairs to eat.
So, William was left alone downstairs to mind the store. Of course, he couldn't just keep reading his book. As a professional, he felt responsible and would occasionally glance up at the customers, even while reading.
"William! So, you really are here," came a voice.
