<human>: Provide a brief overview of the text.

She got a loyalty punch card for free sub sandwiches at Sheetz with the purchase of a sub.  A couple of days ago she showed me the card with all 6 holes punched and told me her friend at work has somehow obtained the special puncher, so now we can get free subs any time.

I told her that is stealing and I don't want anything to do with it.  She apparently didn't understand why it's stealing, so I proceeded to explain and told her I trust she'll do the right thing.

Yesterday, the subject came up and I found out she went ahead and redeemed her free sub with the fraudulent punch card.  She said "You told me you didn't want anything to do with it so I ate it myself and it was good!"

We've been dating for 8 months and until now she has shown good values.  I feel like I don't even know her.  What should I say or do about this recent turn of events?
<bot>: My girlfriend redeemed a fraudulent punch card for a free sub at Sheetz, has no remorse, and I don't like how I feel about her actions.
