New Jersey doesn’t run without Dunkin’.

NJ Transit riders couldn’t get into the Hamilton train station Thursday morning because a doughnut worker who was supposed to open the doors showed up late, the agency told commuters.

“Hi Steve,” someone with the initials T.B. tweeted to an angry rider. “Like previously stated, Dunkin’ Donuts is responsible for opening the doors in the morning at Hamilton station.”

The NJ Transit agent then revealed that it has chronic problems getting the fast food employees to open the station doors on time.

“NJT has spoken to the vendor multiple times,” T.B. tweeted. “If you would like to file a formal complaint, use the link below.”

Riders erupted at the revelation, accusing NJ Transit of not doing enough to make sure passengers can get to their trains.

“Why is a donut shop in charge of opening a train station?” asked Jerry Burke.

NJ Transit officials didn’t immediately return calls for comment.
