I once saw a cashier leave her register open and a man took some money out while she wasn't looking and walked out.

That is an unfortunately common occurrence and is known as "register drift." The cashier must assume the responsibility of watching the register at all times as customers and shoplifters may take the opportunity to steal while the cashier's back is turned. It's sad that someone would take advantage of this and I hope the cashier wasn't too distressed by the experience.
