I had occasion to visit the shrine several times. It is impossible to believe one could enter into the shrimoolasthan of main diety to touch the feet of His Lordship. Even if we believe that, there is enough space for one to offer namaskar. Generally, except for Main Tantri, nobody enters. One has to climb the steps to get inside, so, there is no possibility of others pushing somebody.
It might be true, she could go upto sannidhanam. There are many dieties of Lord are there. Pooja is offered to all of them. Generally there is big queue for visiting those dieties. Because Main Tantri gives prasad if we stand on Q. She must have mistaken them for the main diety.
