Please don't doubt that their Bluetooth database links your Mac address to a wide variety of socioeconomic data gathered from thousands of third-party providers. They don't need the cameras to know who's black or rich or a 4 year old on an old Wi-Fi only iPhone riding in a shopping cart. The cameras certainly help, but they're not required for surveillance pricing.

Probably also a way to track items on the shelves for inventory and ordering. Potentially a way to make sure employees and straightened up the isles/products at the end of the day.

Probably not for surge pricing, they already do all the tracking with Bluetooth for the most part since everyone always has their phone and no longer turns off Bluetooth to save battery.

To elaborate a little, the reason you use specific sand for concrete, and not just any sand is because of viscosity. When you use a sand that is too coarse, the mixture becomes more thick and viscous, which is harder to pour. So you end up adding more water to the recipe to make it pourable which makes it weaker since the ratio of water to cement is thrown off

So uh, most dish washers will heat the water if it comes in too cold. It's a little more expensive than letting the water heater do it, and it'll take longer to finish. you usually just set it to the hottest wash option, and it'll heat the water inside the wash tub once full

The waterproofing schmoo makes me think it's factory. If you're getting 0v at the rear connector there's a break in the line somewhere. You'll have to measure voltage along the wire to see where it drops. You can test the ground by checking for continuity between the negative connector and the body/frame.
