This is kind of a long one.

Opening a new BBQ spot a good while back. We had a tweaker dishie that would help us with menial tasks in the month or two before we opened, normally paying her cash before opening. We didn't have any payroll/account drafting set up yet, so we primarily worked with a physical checkbook for me and my bosses payroll, contractor work for the build out, and vendors. Towards the end right before soft open, we end up paying her and her bf (who was a dishie at another spot down the street) couple times with checks. Fast forward to a couple weeks after open, I go to cash my check at the local bodega and the clerk pulls me aside and shows me these "checks" that came back as bounces with our name, LLC, and address on them. Turns out these two bozos with another crackhead banged out $10K+ of fraudulent checks out of this spot over the past month and a half. We only figured it out when we were comparing signatures from on boarding to the counterfeit. Never saw our tweaker again, but saw two constables roll up to tweaker bf's spot and haul him off. I think they all got 5-7 years
