If there's one thing I learned from reading comix -- specifically, Sam Hurt's magnificent Eyebeam series -- it is that cold pizza has no ownership. Much to his chagrin, the fellow in the online story (videlicet) found that taking leftover pizza led to his termination:
I had been working for a mortgage company as a developer for 18 months and things were going well. Then, one day I saw that a different group in my company had just finished up a pot-luck and had some pizza left over. I thought they would probably end up throwing it away and I was kind of hungry so I went for it ... I took a slice of pizza.Apparently the employees who threw this pot luck were planning to take it home and were offended by my action. Now I thought we were all basically on the same team and if someone didn't like what I did they would tell me so and I would apologize and maybe offer to pay for the pizza. These employees ended up telling their manager, who told her vice president about what I did.
The worst part about this is that I wasn't told about any of this until a month after the incident. No warning, no second chance.
I know that I left an impression because to this day my former coworkers refer to unattended pizza as "programmer bait".
