So, as you can see in the picture, the sign has an arrow pointing you down a certain aisle toward los baños. You can see in the picture what aisle it directs you toward, but if you can't tell from the first picture, here's a close up of the aisle:
Yeah, the sign tells people in search of the bathroom to head down the toilet aisle to get to it. How many people got to that aisle and thought they were already there? Maybe they complained that this store was so cheap they couldn't even bother to put up stalls? Maybe the toilets used to be on the ground level, but people kept unloading turds into them and they had to move them higher to avoid that? Or maybe this is just the overflow for the actual bathrooms whose entrance was at the end of the aisle? You know, if all the stalls in the bathroom are full, you can do your business out here?
Anyway, I thought it was funny.
