I think that more than water, he was scared of the way they behaved, like, he just told them something totally reasonable and they start verbaly attaking him and one of them even threw something at him (good thing it was just water tho), if you ask me those are some crazy bit*hes Σ(  ̄□ ̄||)
But i wont deny the water kind of didn't work how it was supposed to lol I think something like coffee would've been better

I'm sorry, I'm could'nt resist! XD
