I feel that the rules are necessary. While it is nice to thank a collaborator and talk business over a dinner or conclude a deal with a gift, it is influencing the other party in a way that has nothing to do with the actual business. Gifts, dinners and other gestures distract from the main business and can lead to biased decision making that can, in turn, harm the patient. This is almost like bribing the physician. Even if the gesture isn’t very large, there can be a preference towards a company that provides gifts which is a dangerous situation for a healthcare provider.
