Amanda Bynes - who recently had her car impounded and her driving licence suspended - caused concern to shopkeepers at the Kin store in West Hollywood who thought she was "doing drugs" when she refused to come out for a considerable amount of time on Monday afternoon (17.09.12)

A clerk told a source, "I was so worried about her. I didn't know what she was doing in the dressing room. I didn't know if she was overdosing or doing drugs or what."

According to TMZ.com, Bynes made a banging noise on the inside of the changing room every 10 minutes for one hour and 45 minutes.

When they asked her to come out, she refused, telling them she needed "more time".

She eventually exited and purchased a pair of stilettos and some sunglasses, but as she was going to leave she realised she had not paid for a bathing suit under her dress, which she forgot was on and bought while still wearing.
