Our always unpredictable governor did it again this morning.

Mark Dayton surprised everyone in the governor’s reception room — a handful of his commissioners, his staff and a bunch of reporters — by simply disappearing. One moment here, then, zip, gone, through a door that leads from his office to the reception room.

Context: Dayton had called a “media availability’’ for this morning.

The main purpose of this little dog-and-pony show was to announce the establishment of “Minnesota Business First Stop.’’

Essentially, this is what you call non-news. Since the 1970s, Minnesota governors have been calling for one-stop shopping through the governmental labyrinth of agencies and regulations to help people start or expand businesses.

“With Minnesota Business First Stop, any business looking to locate or expand in Minnesota will have one place to call to get the assistance they need,’’ said Dayton, adding that his administration will do everything possible to cut government red tape.

Sounds good. Just as it sounded good when Rudy Perpich was governor, when Arne Carlson was governor, when Jesse Ventura was governor and when Tim Pawlenty was governor.

So why will this be different?

Because this governor really means it, according to Mark Phillips, commissioner of the Department of Employment and Economic Development.

From the first cabinet meeting a year ago, the governor has made it clear that its important for agencies to work together in making the process easier for businesses to develop.

Phillips said that there will be an 800 number for businesses to call, as well as a web page to consult. The effect, he said, will be like a hotel “concierge.’’

Carrying the concierge analogy farther, Phillips said there will be an office “to make all the arrangements and then ask, 'How was your stay?' " at the end of the process.

Dayton said he can be asked in a year how this “new’’ system is working.

Likely, the main reason for today’s not-so-big announcement was to get out in front of Republican legislative leaders, who on Thursday will unveil their plans for “job creators’’ in the state. It’s safe to assume that the Republican leadership will announce that cutting corporate taxes and cutting regulations are the key factors in creating more growth.

What was most unusual about the governor’s event this morning, however, was the way he simply disappeared.

Typically, Dayton hangs on at these press availabilities after making his initial announcement. And these days, that means that Dayton hangs on to take questions about the Vikings stadium. (Reporters feel obligated to ask stadium questions, even though most understand that the answers given now don’t mean much.)

Later today, the stadium working group — which includes a number of legislators and a representative or two from Dayton’s office — is to hold a “marathon meeting’’ on the presentation of a stadium bill in the upcoming legislative session.

Clearly, Dayton didn’t want to talk stadium this morning. So, while a couple of his commissioners were talking about the First Stop iniative, Dayton suddenly did an about face and left the room.

The commissioners were surprised. His staffers were surprised.

Reporters were very surprised.

The first question on everybody’s mind was whether the governor was feeling OK. They were assured that “he’s fine.’’

Like so many Minnesotans, he apparently was tired of stadium talk. He is expected to do stadium talk later.
