Vinzee's Magic Fountain On Court Street Now Only Open Four Days A Week

I noticed just recently that Vinzee's Magic Fountain at 412 Court Street was closed on a Wednesday, when it should have been open.  A few days later, a sign in the window announced the eatery's new "Winter Schedule."  It appears that, until further notice, the joint will only be opened from Thursdays to Sundays.  Though the hamburger joint never seemed to be super popular, the change may frustrate some customers, especially those ordering take-out, since it is not reflected on its web site nor on its Facebook page.
Just two days ago, a reviewer on Yelp wrote:

"What Happened? Strange place closed Mon,Tues,&Wed? what restaurant closes those days?very confusing I guess there going out of Business?I wanted to go back and see my favorite cook but they where closed  I figured I'd give something else a try but i guess there going out of Business Very strange.. And Very sad."

Either Vinzee's can turn a profit by only operating four days a week, or their new schedule is a cost saving measure.  Since this place has had to compete with the recently opened (and much more popular) Five Guys and Moo Burger on Court Street in Cobble Hill, this does not seem like the soundest business decision.
