This is revolting but what shocks me the most is that the producers thought it was okay to allow him to eat it?!
In the early days of BBUS a woman scrubbed the toilet with another guy's toothbrush, production immediately called her to the DR to reprimand her and she was forced to tell him he couldn't use it (she lied and said she accidentally broke it but still). This on a show which is notoriously lenient when it comes to handing out warnings
If I were Bear I'd be ****ing fuming that they sat back and allowed me to eat it knowing full well what she'd done
