I had a blast at Eljay's the other week. I was probably in the store for over an hour looking at all sorts of different books that Eljay's had to offer. I was amazed at the amount of selection they had. I came with the intention of just finding a book to hold me over but left with 5 different books.
The man working the store had a gnarly mustache that was quite impressive and was more than happy to answer any questions that I had about anything. I asked him about a book I was looking for and gave him the wrong author by accident and he noticed my mistake and guided me to the exact location of the book I was talking about. There are thousands of books in Eljay's and he knew the exact location of my particular inquiry. I was astonished.
The amount of books and sections can be a little overwhelming and confusing but like I said, any question I had was answered very thoughtfully and nicely by the man with the 'stache.
