Forfeiture of Deposit

I cannot believe it's come to this, but in light of recent events, I'm forced to add the following language to my cancel policy:

If you're screened and confirmed for a meeting, yet force me to cancel our date for my own safety, due to your own egregious actions prior to our appointment, you will forfeit your deposit.

This includes, but is not limited to:

Any disrespectful speak, vulgarity, references to specific acts and/or threats.
