Was it busy. I've never had that problem there. They don't go by count they go by weight. I've seen that place so busy it needs a revolving door. The count should not change. You get your fish not somebody else's. They made a mistake. I would look at the scale when they weigh it to. I've been suspicious of my fish weighing to much. I hope I can find them this week. Perch for me this year have been evading me like I'm the flu.
