There's no need to 'take them in' unless they are empty. and if they are
empty, it will be obvious.

I have found that it is always good to know how full/empty they are before
taking them in, just so you know you aren't being overcharged. Some
places, too, have a minimum charge. With gas prices going up, no sense
paying even more.
