But it's sigp226's cashier.

The state of the cash register line may not be known until one enters the line.

At that point, the velocity of the line will collapse to a zero state due to quantum physics. This only happens when the line is observed.

I agree.

you must have been ahead of me at Walmart today.

Also, it is impossible to the know the velocity of the cash register line and the gender of the cashier. If the observer finds that the line moves at a specific velocity, say -10, then the sexuality of the cashier will be indeterminate.

No, I am not going to post pictures. I didn't take any pictures because my phone threatened to commit suicide when I activated the camera.

Some of its hair was bright green. It had stupid prison tats and a hole in its head where the Exxon Valdez tried to frack its ear lobe and said, "Fuck it."

The cat was blind the whole time.

So it's actually more like Heisenberg's Shopping Center Uncertainty Principle.  Once you enter a line you've interacted with it, the velocity of the line will change, and you're uncertain of whether it will slow to a crawl or whether all motion within its vicinity will cease completely.
