Being concious gets you 15% off at a high end restaurant in Acapulco

Yesterday night I took my mom to "El Olvido", which is a fabulous high-end restaurant hidden right in the craziness of Acapulco bay. The meal was superb but the most rewarding thing is that I got 15% off, simply because I indicated I did not want bottled water to complement my wine. Instead, I asked for glasses of water to avoid sending two new pet bottles to the landfill. The waiter ended up telling the restaurant manager and at the end of the meal we got a special 15% discount for being eco-conscious. Here is the link to the restaurant: http://www.elolvido.com.mx/
