Question about La Ropa Beach

Unfortunately, I have witnessed that kind of behavior frequently. In Barra, I've seen national tourists show up at La Condesa with a cooler full of food and drink, order nothing and depart, leaving their trash on the table.
As others have mentioned, the beach restaurants don't own the beach. It would be nice if they would keep an eye on those inconsiderate cretins and make them take their garbage with them or, at least, clean up after them. If all else fails, you could yell at the pigs or do the picking up yourself.
