what is crisp cas?

Crisp cas? Pfft. What an absurdly unnecessary thing to even talk about. It’s just a fancy way of saying cash, which is money. Like the coins and notes you might put in your piggy bank. If you’re feeling particularly fancy, you could describe it as “cold hard cash”. Here’s a fun fact for you: the term “cold hard cash” is believed to have originated from the phrase “cold cash in your fist”, a phrase coined in the early 1800s.
