I know its a stretch of a connection but thought worth noting.
I did a surface dig and I see HRC had "a couple of unannounced stops in Manchester", NH 2/11/ 2007. Whilst there she visited 2 pizza restaurants and attend 2 "house party-style" events.
New Hampshire Visits - Democratic Prospects - revised July 14, 2008
On February 11 she started with a couple of unannounced stops in Manchester, first visiting with customers at Pappy's Pizza and Family Restaurant, and then meeting with labor leaders and officials at The Chateau restaurant ; attended a house party-style "Conversation with Granite Staters" at the home of Alan and Joan Reische in Manchester; attended house party-style "Conversation with Granite Staters" at the home of Executive Councilor Debora Pignatelli in Nashua; and conducted a town hall-style "Conversation with Granite Staters" at Keene High School in Keene.
In fact its worth searching for pizza on that page. Some interesting names come up. Biden and Obama being 2.
Katsiantonis and Pappy's Pizza appear in this Article from 2017. funnily enough about money troubles in the local pizza industry.
It is 10 years apart but if this kind of stuff has been going on for years like we all suspect then its entirely possible something happened in 2007.
This is all I could do for now as I'm working on my first post and getting to know my way around steemit.
