For those new to SiennaChat, you must not put anything thin and flat on top of the lid or on a tray inside the well if you opt to buy a tray. When you open the lid, it will eat anything thin and flat in either of these locations. So far, it has eaten a letter, an insurance card, a handicap tag, the keys described above, and probably other unreported items. The keys are the thickest item reported to date. Dealers want big bucks to tear it apart to recover items.
