Okay, I didn't catch it the first time around so I've just re-watched it several times. I'm still a bit confused as to what she actually said, but here's what I got:
Saira is talking about last night
Saira: Is that Chloe asleep? I'll tell you what, she's worn out after all that massage last night. Bloody hell. She's knackered.
Renee: I thought it was how you do it in this country.
Saira: A massage?
Renee: Yeah. I feel f*cked up with you people.
Saira: But I think, yeah, there's lots of ways to give massage but I din't know about that one.
Renee: I [incomprehensible] to tell my mother that there was a STREET where all the prostitutes hung out, and then one day it went on fire. "That they have a monument for, mommy."
Saira: (laughing)
Renee: That's exactly.. That's what I'm taking home. Do you understand that?

No, Renee. I'm afraid I don't.
