Alex may have made the correct, rational choice, given the state of accounting at most corporations. Corporate accounting practices and the budgetary process give different weights to cash and labor. Labor is fixed, and can be grossly wasted without (apparently) affecting the quarterly bottom line. Cash expenditures come directly off profits.
It's shortsighted and irrational, but nearly 100% of corporations operate this way. You can waste a week of your time and nobody complains, but spend a thousand dollars, and the company president is breathing down your neck.
When we answer a question on this forum, we need to understand that the person who needs help may be under irrational, but real, constraints, and offer appropriate advice. Sure, it's good to fight corporate stupidity, but sometimes you just want to get the system back online.
