How to kill a Billionaire

Coffee shop.

Miriam sits alone at the local coffee shop doing work on her laptop
Miriam was a quiet not very sociable person but once you got to know her she was very loving and kind.
As she sips her coffee she drops it all over her laptop.
"OMG!"
Max a very rich but kind guy walks past.
"Oh do you need help with that?"
"That would be great thank you!" Miriam replies.
Max goes and grabs some napkins and Miriam dries the keyboard.
She was so embarrassed.
She thanks him and as Max walks out he drops his wallet but is already gone by the time Miriam tries to give it to him.
