<human>: Can you summarize the given text in a few sentences?

I work in a building that is about half research labs and half offices.  It is owned by the University in my town and they sometimes allow lab equipment sales companies to host small events to show off their products.

On this day a supply company, I'll call them Pipette Tips, Inc., was holding an event and they brought food.  My company is in one of the offices so we weren't interested in the products for sale; however, they had sandwiches.  A few people go down for the sandwiches and one woman, I'll call her Jill, is told that when the event is over the left over sandwiches will be put in the communal refrigerator; anyone is welcome to them.  Jill relayed this to the rest of us.

Some time later a few more of us decided to go down and grab some of the leftover sandwiches.  The kitchen area is next to the front door secretary (FDS) and building manager's (BM) office.  We're taking the sandwich trays out of the fridge, one tray full with maybe 50 sandwiches and the other tray half full, when the BM comes in and says we can't have any and that they're going home with her.  Confused, we go back to our office, hearing FDS and BM bitching quietly to each other about us not asking about the food as we pass by.  Jill hears what happened and gets pissed.  She goes down and calls out FDS and BM saying that they have no right to hoard the sandwiches for themselves when Pipette Tips, Inc paid for them and said anyone could help themselves.  FDS later emailed everyone in the building saying that there were sandwiches in the fridge.

After hearing this, three guys went back down to the kitchen, walking proudly pass FDS and grabbed as many sandwiches as they could carry.  As they left I could see the look of furious defeat on FDS's face.
<bot>: Building manager tries to hoard sandwiches for herself, gets called out, and has to share.  To show her we mean business we took as many sandwiches as we could carry.
