It's a bit of a 'how long is a piece of string' question, I think.
There are girls who see as many as possible, girls who wish they could see loads/as many as possible, and girls who genuinely don't/won't want to see as many as possible for various reasons.
When I only did Out-Calls around a full-time job, I only saw one client a day. And not every day/week.
When I tried working in a parlour, they didn't want me there from 10am till 8pm to see 2 men. In parlours it's all about seeing as many people as possible, which just wasn't for me because personally, it would take its toll on me mentally and physically seeing so many guys for shorter bookings etc.
But yeah, from speaking to the other girls in the parlour I tried working at, they considered good days seeing at least 10+. The work affects us all differently and we all have different limits for how many people we are comfy/happy seeing, for how much etc. x
