Must admit I hesitate to wash my hands in automatic sinks since my bad experience. One of those automatic sinks dispenses soap first then.... no water.
The trick is to activate the Soap dispenser sensor first without getting any soap on your hands, then activate the water sensor and see whether any water is dispensed. - Yes, you run the risk of using the last bit of water in the tank, but that's highly unlikely.
