Ditto on CitySpider's comments. Wafer locks are everywhere. They are found in most cars, desks, filing cabinets and overhead bins. In fact just about every office in the land has dozens. The office ones are usually super-easy (this is one instance when even paperclips can work as a rake and a wrench). You can tell a wafer because when you look inside you see a flat sheet of metal where the pins should be.
Car/Truck wafer locks often use sidebars and are much more challenging. Plus there are high security wafer locks which are a real bear (from what I hear), but I haven't run across any of them yet.
