Problem: The line between accepting gifts and taking bribes may not always be clear. For instance, if a data processing manager decides to purchase mainframe computers for his or her company, it is unethical or illegal for him or her to accept a percentage of the sales as a gift from the seller. Some data processing managers may accept meal vouchers, sports tickets, and other perks from computer salespersons.
Is accepting such gifts ethical? Does it matter if the manager accepts the gifts but promises nothing in return? Why or why not? Cite sources to support your response.
