The Son of Man has come eating and drinking, and you say, ‘Look at him! A glutton and a drunkard, a friend of tax collectors and sinners!’Luke 7:34
In the passage above, Jesus contrasts His life with that of John the Baptist who led a simple life calling the people to repentance.
Jesus continually suprised even His closest followers. In John’s account of Jesus and the woman at the well, notice how the disciples responded to finding Jesus speaking with the woman –
Just then his disciples came back. They marveled that he was talking with a woman, but no one said, “What do you seek?” or, “Why are you talking with her?” So the woman left her water jar and went away into town and said to the people, “Come, see a man who told me all that I ever did. Can this be the Christ?” They went out of the town and were coming to him.John 4:27-30
Jesus wasn’t bound by the expectations of others at any point, because His mission was clear. He came to save us from ourselves and our sin.
