no difference at all

Conversations with S. :
Me:
- Not much difference at all, really, between lap dancing and my line of work. Same attention to make - up, same use and abuse of one's body, strutting one's stuff for money. Having often ghastly punters to deal with. Always being gawped at. I'm pretty much a painted lady, too - quite literally.... 
S. :
- well.. 
Me: 
- The main difference between my work and lap dancing is the working hours. Because of course I tend to work days, not nights.. 
S:
- Surely the main difference is that you wear substantially more clothes when you perform.. 

Right.
