Magistrates banned a teenager from driving for 18 months - but wished him all the best in his efforts to get into the Navy.
Joshua Russell, 19, of Church Row in Honington, admitted drink driving after being stopped by police while driving along Dudley Road in Grantham.
Julian Sheen, defending, said Russell had been out drinking in Grantham but planned to stay at a friend’s house.
He added: “Unfortunately, having had a drink and a friend saying he wanted to get some food he very foolishly chose to drive and that’s how it came about that he was driving.
“He is disappointed with himself for allowing it to happen.
“He thought it would be okay but it wasn’t.
“He was stupid and considerably over the limit.”
Mr Sheen said that Russell was having a particularly bad time having just lost his job as a marine safety officer.
He added: “He is now living at home with his mother and is now out of work.
“He is planning to join the Navy in three to six months’ time.”
Chair of magistrates George Hoyles told Russell: “This momentary lapse is going to cost you dearly.”
But added: “You have a lot to look forward to and I hope you get in the Navy.”
Russell was disqualified from driving for 18 months and fined £110.
He must also pay £85 costs and a £20 surcharge.
