I think basically BB wouldn't give them what Ben and a number of other housemates wanted. Ava wanted to get tofu (you can see a video of her talking about it on there somewhere - she's saying it's in the staples), and the budget was less than it usually was as BB was fining them for swearing. Then BB later was saying some can use the chat room (it ended up being angie and estelle - you can see the video on the site of them deciding), but Ben wasn't clear on what he meant and tried to reconfirm. Bb said he didn't say that. Then Ben got mad at Big Brother saying yeah seems you haven't taken your medication either, then Ben got put in the punishment room for disrespecting Big Brother.
So I think maybe the tofu incident from what I could figure out is Ben trying to take charge and getting it perhaps but Bb shutting their requests down and so Ben got mad at BB.
