Yes!!
It's even more obvious when you look at how she hurriedly tries to explain how she got injured at work. She talks very fast, trying to say every little thing she wants the jury to hear about that incident. But on the 19.65 purchase, she didn't try to come up with any explanation.
Very very telling.
I think she would have preferred to use cash for the gas can fill-ups for obvious reasons.
At 4 am she finds herself at a gas station with the mini-mart closed and she's forced to use a card. I bet she remembers that. Kind of an oh sh** mo,ent.
There is another gas place across the street, w/ a burger king inside. That was probably closed.
She remembers the incident and knows damn well Juan knows that gas station was closed.
she was afraid of the credit card/receipt ruse being uncovered. She thought she got away with it.
Bad surprises leave her speechless
