You can see on the left where they tried then realized it was way too big of a task. I probably would have tried a little harder to get some white in the right spot, but definitely not perfectly. Not even close. I ain't mad
This just makes sense. They most likely did a repair or something underneath the bricks. To do this they took them all out and put them in a big pile, did the work and then started to put them back.
Now are you going to just put the bricks back quick and efficiently since all the bricks are the same, or are you going to inspect nearly every single brick with a line to ensure you are placing the correct brick in place?
Dude I love puzzles and would love to drag solving that one out as long as possible bc money. But you know the supervisor is telling them to hurry up and ignore the lines so his boss can make some more money.
It’s a feature, not a bug. You can take them out to work on underground infrastructure, or even it out if there’s a slump, and replace the same materials, instead of having to jackhammer shit up and pour new concrete/asphalt.
