Wow...

If anything has happened between your friend and yourself that would have a negative impact on him, then I highly suggest making a little note to the head manager about this. He could be using his power to just make you more miserable and holding a grudge against you.

But, if he doesn't have an issue with you that is personal, I still would file the complaint anyway. Make sure that if the human resources people come and check up on it, you tell them that you have a relationship with him (friendly). And with the notes that you recorded, you should be able to have a case and not have the management pull a "We gave him a warning and he is abusing his lunch priveleges".

E-mail me, Sam and I want to talk to you more about it. Sounds a bit serious. john.a.canning@gmail.com
