My neighbor in Tucson did this to his patio last summer and it actually held for like five months. He used the chicken flavored ones though, which I think made the difference because they've got more oil in the seasoning. The worst part was the smell when it rained, smelled like a dorm room for two weeks straight. Now there's a family of crickets living in the crack because they like the crumbs.

Wet shoes on the porch every Sunday is already strange enough on its own, but the flashlight to her face takes it to a whole different level. You handled this with way more patience than most people would, giving it three weeks before setting up the camera. That backward walking thing is what really gets me, it sounds like she knew exactly where that camera was and wanted to make sure you saw her. I would check if that video captured anything else, like her stopping at the end of your driveway or looking back at the house. Nobody does that kind of thing by accident, and you are right to be worried. Keep that video saved somewhere safe, and maybe mention it to the local police just to have it on record if things escalate.

Buddy of mine had something similar happen with a contractor years ago. He paid the guy upfront for a kitchen remodel, and the guy kept sending these vague invoices for "materials" that never showed up. Then one day the invoice had his address listed as the job site but the materials were going to some other town. That's how he found out the guy was building a shed at his own house. Took him six months and a lawyer to get his money back, and even then he only got half. Sleep wasn't the only thing he lost, his trust in anyone with a toolbox went right out the window too.

Wait till they snap like the rest of us. Stopping mid-shift to swap teeth just means you're eating the downtime twice, once for the change and once for the catch-up. You got lucky this time, but that 45 minutes would've been better spent grinding through the clay.

Honestly, did you just cut the discount or actually fix the problem?
