Last night at a book signing, there were quite a few SS's around.
First, I thought the bookstore that arranged the signing was a bit SS. They gave almost no details about the actual signing out, so most of the people I talked to didn't realize that they had to buy a copy of the book at one particular bookstore, but that the signing would be in a different city (granted, the cities are both part of the greater metro area, but still...it's a weird detail to leave out!). When I tried asking the staff at the bookstore for some more information, I was given a piece of paper with the comment, "Here's everything you need to know!" and the salesperson walked off.
Second, the details that we were given said something to the effect of "the author will sign all copies of *book that just came out* and one other item". Apparently this was a challenge and some people were showing up with stacks of 8-12 copies of the book that just came out! After seeing some of the stacks, I wasn't surprised when the author mentioned he'd been up until 3 am at the last signing.
The last SS I saw before leaving actually was heard before I saw it. Throughout the author's reading and Q&A session, there was what sounded like a husky talking in the theater. The author had mentioned that his dog was backstage, so that's what I assumed was the noise. Turned out someone had the worst trained "service dog" ever at the signing. It was a husky, wearing a service vest. The husky talked, tried to make friends with people by shoving its nose into their faces, and was barely leash trained, since it was towing the owner down the aisle! The guy holding the husky's leash didn't apologize to anyone for his ill-trained dog. Someone said something (I was a few rows away and didn't hear what) and the guy responded by flipping the other person off.
That was the point at which I left. I really wanted to meet the author, but I really didn't want to spend the time needed (or deal with the SS people!). They had stacks of signed books out front that you could exchange your book for, and I ended up doing that.
