Showed up at 4:19p to buy some pastries (of which there were plenty). Sign said they closed at 4:30p but we were turned away and told that they decided to close at 4p. Very unprofessional way to conduct business. At least 4 other people tried to enter before 4:30p as I wrote this. Now they've lost business and received a bad review.
