Running Out The Hose

No, I don't think there's anything seriously wrong with this sign.

But I was just thinking, why is it "running out the hose"? I guess perhaps it refers to the act of rolling out the hose, since the hose must be pretty long. But why "run out", and not "roll out", or something else?

I checked "run out" in Dictionary.com, and the results are below:

run out:

1. to terminate; expire

2. to become used up

3. to drive out; expel

I guess none of the above meanings of "run out" apply in this case. I checked Oxford Advanced Learner's Dictionary too, and the results are somewhat similar.

Then I typed "running out the hose" in Google, and it gave me these, among many others:

1. running out a length of hose...

2. running out dutch rolled hose...

3. running out the main hose line...

4. open valve before running out hose...

Hmm.. I guess "run out" does collocate with "hose" then. =)
