It really pays when a star forgets their money at home while ducking out to grab a quick yogurt.

Charlize Theron recently gapped out bringing along her purse when she visited a Pinkberry yogurt shop in Hollywood recently.

She ordered a chocolate hazelnet with chocolate shavings, then discovered she forgot her cash. She informed the lady working behind the counter she'd be back to pay the $3.75 tab.

She made good on her promise and then some. Charlize returned with her boyfriend Sean Penn and slipped the woman a $100.00 bill and told her to keep the change.

That's a $96.25 tip. I'm sure the employee gave Charlize permission to forget her money again sometime soon. Or at least on the days she is scheduled to work.

Here's a video of the Pinkberry employee talking about what happened.
