Both teams were using bleach & Red Chillies to be fair. Clearly Sid Dey had a worse reaction than anyone else but not like the other team wasn't using the chemical on Asim & Abu.
a) It's BB's responsibility to ensure the game is played in a safe way and no harmful substances are used.
b) It's Sid Dey's or whoever else that is being tortured to understand the game is not worth skin or any other sort of short/long term damage.
c) It's the person responsible for torturing to play in a safe manner and make the opposing team understand the same what substances are allowed and what are not so it's an equal ground for both teams.
In previous season, both teams agreed that what substances they would allow and disallow in dangerous tasks, especially ones that had to do with ingesting foods....because the sadistic BB would hardly care if they made them drink bleach next time. The housemates should do the same here. Come to a common understanding and play the game in a safe manner.
