I read a lot of Posts and find them very interesting and I get many ideas, however when I read a post that either frowns on what a DJ is doing I say to myself, Some of these people have another job, and have to follow the owners rules, this DJ bussiness is their own business and they should be able to do whatever they want, there are no rules except for common courtesy, legal behavior etc. If someone wants to barter, give a discount, work for nothing, etc. it is their privilage as the owners of their business to do so.
