I'm astounded that they didn't tell her to come to the DR immediately and just sat back and allowed Bear to eat the sandwich
I mentioned this in a thread earlier but in the early days of BBUS a woman once scrubbed the toilet with another guy's toothbrush and production immediately reprimanded her and forced her to tell him not to use it (although she lied and told him she accidentally broke it). This happened on a show which is notoriously lenient when it comes to intervening and handing out warnings
They have a duty of care towards the housemates and the fact they let this play out is appalling, if I were Bear I'd probably be more angry with the producers knowing full well they could've stopped it. I mean would there be any grounds for a legal challenge here?
