"My hourly rate as CEO of this Corporation is HK$1900 or US$247.00 per hour.

Think that with a discount, US$18,000 should be sufficient to cover all my time related costs, fixing ALL code instances, for ALL the aforestated reasons..."

Then he adds:

"Thanks a bunch for being SO HELPFUL !!!"

His first post was on 2012-06-17 21:06:44 PDT and his last post was on 2012-06-19 23:11:22 PDT, so it's only been ~50 hrs since he posted it until he asked for the money.
