should schools raise money by selling candy and sugary soft drinks to students?

High school is full of class work, tests, friends,organization in which students are involved. According to my perception such items as candy and sodas should be allowed to be sold in school for fundraising. The money goes towards great causes. It can be used make the school a better place. Fund-raising is a great way to teach students about customer service skills and goal setting.it teaches students how to compromise in group situations and it teaches them how to act appropriately in leadership and subordinate roles.
