I would guess that water cannot remain there for infinity, so the
concrete is going to dry eventually. If it's constantly being disturbed,
I assume what you get is a bunch of concrete gravel.

Mmm, seems plausible.
FWIW, as I understand it, it's not the water as such. The setting of
concrete involves a chemical reaction rather than the mere removal of
the water.

I don't know if disturbing the concrete while it's drying messes up
with those reactions, but if it does, you would probably eventually get
some kind of dust or gravel.

You wind up with a cement truck that you'll have to clean out with a
jackhammer.

The evaporation of the water causes the chemical reaction.
To delay the setting, you can add more water, but then you wind up with
gravel in very runny concrete that doesn't stick. If you don't add water,
then eventually the concrete will set, even being agigated. It just won't
stick to anything. You'll have a whole bunch of gravel covered with a thin
layer of concrete.

Or the "earlier" means "last week" oslt for them. Anyway, there's 600000
quote-id's between those two, so if bash.org increases them logically,
there's probably a bit more time between them than it seems at first sight.

I sent a bunch of garbage to one of those places,
but I made sure not to put my address on any of the
junk in the envelope.
...
A long time ago we had Sprint LD service, one of
the employees stole our credit card number. The
crooks got arested because they used the counterfit
card to pay their own electric bill. Dumb loosers!
Anyway, Sprint got dropped, but several times
in the following years they would bill very small
amounts. We didn't owe it, they just never purged
their system. So here's a bill, you owe us $0.12,
even though you haven't used our service in years,
and when you did, we stole from you.

Maybe the drivers just carry some of this for emergency use:

I have shopped in a supermarket that often has buy 1 get 1 free offers.
The bill looks like this:
They often sell short dated fresh produce at reduced prices, with the resulting
bill:
It makes for interesting and profitable shopping.
Cheers,
Peter

My mum would TOTALLY DO THIS! o_O
then handing the cashier a huge lump of coupons. (The look on her face
was... enough to cause fatalities!) When she finally finished scanning
obviously, is still an *absurd* amount of money to spend on food for
just two people, but hey...)
