I'm not responsible for the buildings or teams in SJC15 and the OP knows that. The people who work with me at Cisco know that when I say I'll help, I do.
The same can be said for people who know David outside of Cisco too. I know David from SHDH, EveryDNS, & OpenDNS. He's a man of his word.
Caveating your offer of support three or four times signals hostility not helpfulness.
Any rational actor reading that statement would assume you’d forward their message onto HR without a real response. And make note of the complainer in question.
If you can’t be concrete with your words, why even bother?
"I'll see if I can give you some pointers of how to make some progress on that ask"
probably means
"I'm not the god damn office facilities manager, and I'm not spending my limited time and social capital to quarterback your request for you, but I'll see if I can figure out who in god's name in this 70,000+ person company you should talk to, and tips for how you might convince them to change their budget to give you free snacks".
Spoken like a true Cisco executive. You could have just said "I'm supportive but it's out of my hands."
Or perhaps, no reply at all.
