Preston said:Some of the water blaster's had black duct tape over them... while everyone else was using the working one's I ripped the tape off and put in all of my quarter's and I blasted I think 23 boats, with no problem.
Preston, the contracted company, Elaut USA are the ones that maintain those water blasters. They typically use black tape to cover the coin entrance to indicate that the machine has experienced an error. DO NOT go ripping off anything from anywhere. That is like ignoring a stop sign that doesn't have the word stop written on it. My biggest pet peeve is when a guest is not directly told something, but it is implied and they completely ignore what should be an obvious sign. This is the reason why the warning label, "Cation: Contents Hot" is now posted on every coffee cup. It really is ridiculous.
That said, just because you were able to put coins in and use the machine does not mean it is fully operational. There can be an inside malfunction that could need fixing. For example, the counter inside the machine that keeps track of the money earned. That is very important part, even though it may not affect the actual operation of the machine.
