Why should there be rigid timings for Boi Mela?

Yesterday I visited the book fair around noon and all I could see were closed stalls and the security dismissing people, saying that the fair won't start until 3 pm. What is this new rule? People from all over the country spend their valuable time and money to visit the book fair, only to be dismissed in this way.

Why let the fair continue if people for whom it is held are deprived of it? So many people are missing out on the event due to this ridiculous rule. Also, where was it stated in the first place that no one will be allowed entry before 3 pm? People deserve to be reimbursed the commute fare they are spending on their way in, especially when they're being sent back in this manner. It's a matter of concern for the general public and we demand an explanation for this rule!
