Amanda Bynes Wait, I Have to Pay for This Shirt?? Allegedly Caught Red-Handed AGAIN

Amanda Bynes
was accused of shoplifting in New York City TWICE Wednesday -- TMZ has learned she was also caught trying to swipe merch from a women's clothing store ... one hour before the Barneys bust.

According to our sources, employees at Pookie & Sebastian began following Bynes around the store because she was acting suspicious. We're told they didn't recognize it was Amanda, and just thought she was a "half-naked, homeless crackhead."

Customers tell us Bynes was dancing and muttering about plastic surgery -- but eventually she tried to bolt with a shirt stuffed between her arms. When an employee stopped her and asked if she was going to pay, Amanda said ... "Do I really have to buy this?"

The answer, of course, was yes -- and we're told Bynes was actually cooperative ... whipping out a credit card to cover the $128. 

As TMZ first reported, Bynes was also nabbed by security at Barneys while trying to walk out with a $200 hat.
