I work at a huge company which has over 500.000 employees worldwide.
We have a huge cafeteria where we go to eat our lunch, we have a trading book shelve in there as well.
I sneakily snuck in one of my proof copies on the shelve and wrote a bit on the first blank page.
This morning when I checked my book was no longer there, so one of my colleagues took it to read it, I do hope they leave a message here so I know if they liked it or not.
I redacted the name of the company I work for though, not sure if they want to be associated with a book as horrible as this one :P
