The 18-year-old, who can not be named for legal reasons, has been banned from going out between 6pm on Saturday to 6am on Sunday.
The binge-drinking lout was slapped with the order by Alnwick magistrates on Monday after he tormented Rahim Uddin, owner of Barresdale Triple Diner, Sycamore Avenue, Alnwick, with a barrage of drunken insults on two separate occasions. He pleaded guilty to two charges of racially aggravated harassment.
Alnwick Youth Court was told that Mr Uddin lives above the shop with his family, including his young children.
The bench heard that the incidents, which occurred on June 19 and June 29 this year, happened after hours and included the teenager banging and head-butting the window of the shop and making racist remarks.
One of his rampages was fuelled by a cocktail of lager and vodka.
The frightening storm of abuse left Mr Uddin fearing for the safety of his family.
In a statement read out in court by prosecutor Derek Walden, Mr Uddin said: "I am worried about the effect this will have on my family.
"My children mix well with the local community. We get on well with everyone else and I want my children to be happy here. I do not want to fight.
"My mother was with us at the time and she was frightened by the noise and she said she had never heard anything like this before.
"I don't want to have any problems at the shop. If he can't behave then he can't come into my shop."
The bench heard how the teenager had been a regular customer of the takeaway store and that the racial attacks had been fuelled by drink.
Steven Davies, defending, said: "He (the defendant) has helped them in the past advertising their business. But what is clear is that for some reason, when in drink, he has resorted to behaving in this manner."
But the heavy-drinking youngster is now getting help for his alcohol habit.
Mr Davies added: "He has taken it upon himself to meet with a specialist worker to address the problem and he has cut down significantly on his drink."
Magistrates said they wanted to extend the curfew order, also banning the teenager on a Friday night. But they were unable to because of the teenager's possible work commitments which would see him move down south throughout the week.
But he was given a community order and punishment rehabilitation order for one year and made to pay £60 court costs.
Chairman of the bench, Virginia Armstrong said: "We are unable to put it on Friday night because of the difficulty of saying when you will be back home.
"We are putting the responsibility in your hands for keeping away from the Uddins."
And the teenager, who had subjected another Alnwick resident to a torrent of racial abuse in July last year, was warned that if a similar incident occurred, he would face jail.
Mrs Armstrong said: "You have committed three racially aggressive crimes.
"If you commit another there will be no question but to send you to prison."
