What kit is that I haven't seen it?

With an escort ask anything you want they are used to it.

If that's so important to you, just ask them, don't worry about an outcome. There are plenty fish in the sea. 

No BB

Some might consent if you do the same. And some would definitely tell off. Are you planning a BB? 

I hope to ask the escort if a rapid screening for infectious diseases can be conducted after entering the room (using a test kit, with results available in 15 minutes), but such a question might be considered offensive. I wonder if I can do this?
