It always depends upon where the gift came from. If your friend gives you a gift worth any amount of money and is not a stakeholder in any way in whatever you're doing, it's perfectly all right, but if you receive a gift from somebody who is looking for you to make a decision in his or her favour in the near future, then it's probably not all right if it's $50. It depends upon the circumstances.
