Hello everyone. Recently, I messed up and had a theft happen due to my carelessness and received a PDD (I think it was called that). Anyways, even more recently I accepted a fake bill. I used the marker to check it and it didn't smudge, but the GSA informed me it was a fraudulent bill. I am very regretful and worried I will be fired very soon. I feel awful that I let this happen and feel like I am a liability due to my lack of common sense. However, I really need this job and want to do whatever it takes to keep it. How should I apologize to the store and AP so they can forgive me and let me stay?
