I used to work at a small privately owned copy store. Like a FedEx Kinkos. We did it all, copies, shipping, great customer service. Well anyways, as it was small there was only 3 of us that worked there, my boss, my coworker, and me. Like anywhere else we had customers that you could NOT please. Literally my first week there, I had a customer cuss me out because the ESTIMATE of a shipping price I gave him was ONE DOLLAR OFF!

Well, to deal with the stress, my boss allowed us to play custom maps of Ghost Recon the last hour of the day. Who were the enemies we shot on these maps? Customers we hated! Also, he played with us... AND he let us play World of Warcraft... as he played that with us too.

Best. Job. Ever.

Sadly due to economy, and bad investments, he had to close the store down, after 20 years of business.

TL;DR - I had a boss who let us play video games the last hour of each workday.
