Derek Farrell (19) was charged over the alleged raid in Crumlin.
He was granted bail and the case against him was adjourned at Dublin District Court.
Mr Farrell, with an address at Fortlawn Avenue, Blanchardstown, is charged with robbing staff of €179 in cash and cigarette papers worth €73 at Applegreen, Parnell Road, Crumlin on January 10.
He is also charged with causing €500 worth of damage to a counter.
Garda David Morris told Judge Deirdre Gearty the accused made no reply to either charge after caution and was handed copies of the charges sheets.
There was no garda objection to bail subject to conditions. Judge Gearty granted bail on condition the accused lives at his home address, observes a curfew and signs on daily at Blanchardstown Garda Station.
