Alan Gellen is the facilities manager for the city of Milwaukee and makes all final decisions on purchasing items such as chairs, lights and other supplies and materials. Alan also makes the final decisions for the award of contract to food vendors at events sites. Grand Beef Franks has submitted a bid to be one of the city's vendors. Alan went to school with Grand Beef's owner, Steve Grand, who phones Alan and explains that Grand Beef owns a condominium in Maui that Alan could use. Steve's offer to Alan is: "All it would cost you for a vacation is your airfare. The condo is fully stocked with food. Just let me know." Should Alan take the offer? Would you? Be sure to determine which category of ethical values (include at least two ethical dilemmas) this situation involves and to apply two ethical models as you resolve the question of whether Alan should accept the invitation.
