Back in my witness early 20's, a number of us young bloods from the local congo would sell a cleaning device from door to door to supplement our income. It was a simple handle with a sort of bulldog clip on the end into which one could fasten a brush or duster or sponge. A local brother would make them and sell them to us for 50 pence each. We would then sell them marked up 100% for £1 each. Sell ten a day and we'd made a fiver. WooHoo!
Then we had a new young very holy bro move in who wanted to be part of our little sales team. He immediately chastised us for girl-watching. Then he objected to us only working until we'd sold our ten a day, insisting that we should work all day no matter how well we did. Then he said we were being extortionate in our prices and that we should only go for a 50% mark up. So we told him to go work on his own.
And then he told us - he had got the calling, he was of the remnant! So yeah, that all fitted right in..
