Which brings to mind, a story my Army buddy from Vermont related.
It seems a youngster, fresh out of high shool, went to work in a local sawmill. After a few days, and likely wanting to fit into the culture, he noticed most of the sawyers chewed "backy", so he started 'borrowing' a chew from the old hands.
After a few days, he noticed a small difference in the tobacco..so he asked one of the donators.. "I notice that when I get a chew from you, your chew is more moist than the others, how is that?"
The old timer replied.."well you see, every now nad then, I spits back into the pouch."
..Guess the kid quit chewing, or began buying his own tobacco..
Around here at the general store, the big wheel of cheddar cheese ..every now and then, donated a 'sliver'..of it's ambrosia..
