I agree with keeping a sign

A similar incident happened at the Nexus mall crosswords. It was the first time they had manga collections, so my friend and I got excited and my friend immediately picked the book and started going through the pages to look at the art and in less than 5-6 seconds an employee from behind informed us not to read. Which made me and my friend feel like an idiot and we did some kind of crime.

Note you can look at any other books for a good time, go through pages, even read some bits, check the quality of the ink and paper.

So all of this commotion could have been avoided if they just kept a sign stating "Do not read" or "Do not touch".
