Quick question about apostilles process

Since I'm stuck waiting hours at MI SOS ...and have no clue what to expect...this Supercenter was listed at a walk-in apostiling place...does that mean they can authenticate on the spot? Or that I can turn in the doc here instead of mailing them??? No information can be found on the state's website...what were others' experiences?

Holy cow! I never expected 'walk in' meant she would apostilled right in front to of me! That was awesome... And cheap...$1 per document

Where is this?  A miracle for sure.

Michigan Secretary of State office...not normally a place where things get done faster....HAHAHA
