Just checked my bank app. I've got insufficient funds for that dinner tonight.

Typical. Just shell out the cash later, I'll cover you.

Fatima uses 'insufficient funds', a common formal banking term, to explain she is broke. Maya responds with the phrasal verb 'shell out', meaning to pay for something, often reluctantly.
