[TowerTalk] Concrete Set Time

[John Kemker]

That's why you pay for the test.  If what they pour doesn't pass the 
test, they have to come back out and replace what they pour.  If you let 
them know ahead of time that you're going to pay for the test, they'll 
likely make extra sure to bring the right mix.
