she did it quite blatantly in front of several HMs in the kitchen , and no-one said anything in objection .

it looked to me like Grant and Saira saw her doing it but which others ?

.

From the VT I watched, Ricky but he was shocked and walked out with his hands in the air saying "oh my god, oh my god". Pretty sure that was after the sandwich and before she did it into the tea.

Grant was there and Saira who carried on talking to Aubrey, whilst while she was spitting into the cup of tea.

I thought BB saw everything so why didn't they do anything when they saw the spitting incident on camera.
