Greasing new wheel bearings and hub.

In years past, I have worked for a couple of big shops. One shop we did all the repair work for all the Hillsborough County Sheriffs Dept. Which was a big contract. The owner of the shop would climb your *** if you filled the void. Fast forward 10 years I Work for Tampa Armature works. The old man I worked under use to tell me" You fill that hub up, I ain't gonna loose a bearing over 50 cents worth of grease." Since I can't remember ever loosing one, I guess there is no right or wrong way to do it.
