Stationary cart

I hadn't been working here very long when the old, huge stationary cart disappeared from the kids' dept., so I don't really know what it was like to have it here, except for my brief experience last summer. Which probably makes it dumb for me to open this subject in this public forum, rather than speaking directly to the Queen. I plead naivete!

Here's the thing: I guess I haven't really noticed that the other shelves are significantly more messed up as a result of losing the "proper" place for kids and parents to set down books without reshelving them--but I know it's easier for *me* to direct a patron to bring any books they don't want up to me at the gazebo to deal with...and it makes it simpler for *me* to deal with them if I simply bring a cart along with me at the start of my shift, which I can either take up to the circ desk when I depart (I made a laminated sign that reads, "Please rough sort for re-shelving," which is stashed up with the "Shelve First" signs on top of the stacks that contain staff holds), or I can snag a page who is emptying a cart, and ask them to swap their empty cart for my full one, which they then rough-sort for re-shelving up behind the circ desk.

I have the general feeling that at least some others have "borrowed" my method of using a non-stationary "stationary" cart, and I wondered whether I was either breaking some taboo by doing this, or whether we shouldn't all work in coordination to train patrons to deposit books they don't need in this location....?
