On your way to an escort?

Perfectly fine. Always wearing a sunglasses if it's daytime to disguise a bit.  

There is no shame in doing it. It's just business like any other. 

I get pretty anxious before heading down to an incall location, always worrying if anyone who knows me would see me in parts of the city i don't usually go to. So i always have an excuse or two ready for "what you're doing here" type of questions...
