Context: I had to verify in a couple of places to make sure the maid had n't just reset my clock while I was out . Saturday was kind of a blur , to be honest . I had an autographing session that was n't a complete failure , but I was sitting next to Stephen Baxter , who had a non - stop line and people having to get in line over and over again because of the three - item limit . It did n't help that only one dealer in the dealers ' room had my books at all , and they sold out on the first day .

Answer:

Because there was a three item limit and more than one person signing books and the people wanted more than one item .



Why did people have to get in the line over again ?
