Have you hear of the latest deterant to drunk driving, the talking urinal? Restaurants and bars in New Mexico have deployed them into the restrooms. A flirty woman’s voice comes across saying, “Hey, how are you going to get home? Have you had too much to drink?” A more effective approach might be to use a stern male voice such as, “Hey you! You can’t see me but I’m a cop and I’ll be looking out for you on the road.”
If a RID person were to receive such a message they would respond, “I’m sorry I can’t hear you with the water running.”
