Actually, this store is a good thrift store. There are lots of items, and a friendly staff. The above reviewer is obviously an amateur at thrift store shopping. The "pencil" you refer to is called a China Marker or Grease Pencil. These are used so the plates are not damaged by forcefully applying a sticker with a tagging device, which may ruin china or porcelain. Yes, WD-40 will get it off, and Yes, the WD-40 will come off in the dishwasher. You were going to wash these before you used them, right? There are TONS of clothes, and misc items to be perused!
