What are the various industry schemes that you guys know of?

I used to sell is also selling cell phones, that time the domestic miscellaneous machine profit is the biggest. The manager gave the task, must sell a few units. Once, a father and son with a broken basket, wearing a very broken, the child's father said he just sold the crops, the school year, to buy a cell phone for the child. The manager let me make a strong recommendation to them miscellaneous brands, but I know that miscellaneous brands are not durable, two falls either the speaker is broken, or the screen is broken. So, I have been advising them to buy Nokia, thinking that it is not easy for them to earn money, so they should buy a durable one and use it for a longer time. Later, they bought Nokia went away, the manager began to give me a lesson, and give me to increase the task, but also asked me just how good the opportunity, five or six hundred profit is not earned, I said conscience, can not bear to earn their money, and then I do not meet the standard of the task each month, (because I do not want to sell miscellaneous pits), was dismissed.
