Why use thrust reversers?

I see a lot of planes using thrust reversers and stopping in the middle of the rwyrunway in plane spotting vidsvideos, but I don't understand why they do it when they can obviously not use the reversers and still stop safely. 

Also, doesn't it waste fuel? Don't airlines prioritize fuel savings over stopping faster? Why are reversers used even when they don't need to be used?
