An unsealed envelope left in plain sight is a great way to handle the donation. 

Please don't hand the envelope to me directly. 

I'd really appreciate it if you gave me a little privacy just then so I can put the envelope safely away.  

Might be a good time to wash your hands?

It's important to remember to confirm you're visit about 90 minutes ahead of time.

Also, a quick text or email the day before would also be super appreciated.

Aggressive behavior will not be tolerated and will result in the early termination of our time together.

Don't be alarmed if I make a "safety text" at the beginning of our time alone. 

It's something I have to do.  

My girlfriend and I do this for one another so that we each know that the other is safe.

Minty breath and being shower fresh are absolute musts.

You're always welcome to use the shower here if you need. 

I respect the personal choices of every individual. 

However possession and/or use of illegal drugs will not be tolerated in my presence. 

Failure to respect that boundary will result in the immediate termination of our time together.

Schedules change, life happens. 

But if we've planned on some time alone and you can't make it please let me know as soon as you know.

Show me that you really value my time and me as a person.
