What is the Car wash hose for?

There is a hose that lays on the front entrance right before you go in. Its attached to a box but don't think it had wires inside nor do I think water comes out.


Oh, ive seen those, but the problem is, its all Automated, no ones there to hear anything, lol. Plus the car was is modern with jet dryers. Wish i could post pics so you guys can see it.

    It is most likely a signal line, like in older or smaller gas stations. The line is plugged at one end, and the other is connected to a pneumatic (air operated) bell.

    This alerts the car wash operator that another car has arrived.
