I dont know anything about your shop or how much is is going to ask for, but the shop I used to work in had a fairly similiar suit against it (although without all the extra drama). A guy was carrying in a dual 15 prefab sealed box and he bumped into one of the sales people, box fell and he broke his foot. He ended up sueing the shop for like 10k, instead of dealing with the courts and bad publicity the owner ended up settling for like 7500 plus a new box to replace his POS prefab.
