People at casino asking you for cash for Cash app, Venmo, Zelle, etc…

At the casinos I play at, recs and regs frequently ask each other for cash and they transfer over funds on Cash App, Venmo, PayPal, Apple Pay, or Zelle in exchange. Sometimes a huge whale will be the one asking for cash after busting many times and regs are always happy to give them more cash to keep them in the game.

Surprisingly I haven’t heard of anyone getting stiffed.

Anyone have stories and experiences of getting stiffed? On which platform?

Anyone get audited from the cash transfers or having monetary transactions with shady people (plenty of those in the casino)?
