Redditors who worked the register at McDonald's, why do you need to call a higher-up to void an order? Why aren't you authorized to void mistaken orders by yourself? | Ex-McManager here. It depends on corporate or franchise. Corporate is slightly laxer, there's usually a dollar amount before you get locked out. it's for exactly the above reason.

Why isn't my cable internet travelling over the same wires as instantaneous as watching an HD show on the TV? | cable television does , it's just that the bandwidth used is all on a reserved pipe.

These are super secure buildings, with well trained staff, ... |
Why are luminance levels measured on a scale of 0-255? | If you were working in decimal, you'd probably choose a range of 0 to 99 or 0 to 999, getting as many values as possible with 2 or 3 digits. Computers work in binary, so it makes sense to use a range that matches a number of binary digits. 0 to 255 fits in 8 binary digits, or one byte.0-255 is very convenient because i... |
How does jumping off a bridge into a body of water kill you? | When you're moving very fast and then suddenly stop your organs tend to keep moving for a short distance when the rest of you is stopped.

Why do humans assume that we need earth conditions for life to exist? Is it not possible that other life forms could exist under different conditions? | We don't assume that.

If our actions are determined, how can they have any meaning? | The old saying goes, 'if a tree falls in the forest and no one is around to hear it, does it make a sound?

Please explain radiation and exposure to me. I can't grasp the concept of it not being a gas/object/liquid etc. | I tell people to think of it like a light bulb.
