You laugh, but many people fail the aquafresh-paint job differences training at X-Jet and are ruined for life. They can't remember the key differences for the test, and upon failing are forced to drop out of the program for the fast-food industry. However the latter has been shown to help remedy slowness, and many reapply and are able to pass differences training the second time. X-Jet training recognizes the problem and has begun testing of pc-based training aids that introduce candidates to generic toothpaste, soap and shampoo schemes before moving on to the aquafresh paint scheme. Results are encouraging. Just kidding... got a few minutes to kill.
