Hopewell: A 78-year-old woman decided to spend her final hours last month — to her very last breath — in the now-shuttered New Jersey luncheonette she spent more than three decades running.

The lights dimmed on Chubby’s Luncheonette three years ago, but it was so special to former owner Carol ‘Chubby’ Montello that she decided she wanted to die in the Hopewell diner.

Montello worked in the luncheonette before buying it in 1979 and didn’t make many changes to its 1950s decor, with framed newspaper articles, baseball cards and toys lining the walls.

Montello had established unofficial rules to being anointed a regular in the establishment and those customers normally made it to the diner before she did, said Joanne Farrugia, who was raised by Montello along with and her two sisters, Michelle Hamilton and Lyn Farrugia.

She left the door open 24-7 so regulars could make coffee and heat muffins before she arrived in the morning. After the store closed, Montello often sat inside the diner since she lived above it.

Last month, Montello went to the hospital, but didn’t want to stay. So her close ones arranged to put her hospital bed in Chubby’s alongside the tables, and she died there.
