Potty Training Gone Wrong

So, I was at work (weekday restaurant) this afternoon cleaning up. The restaurant was still open, but I was finished with tables, so I was kind of incognito as I stuffed sugar into the little caddies on the table.

I see a little boy, maybe 3 years old, doing a little "potty dance," and then I hear the mother ask if he needs to go "potty." The boy says no. Then the mother says, (and I kid you not) "Do you need to go out in the grass?" He says yes and she swoops him up and out the front door. Surely I didn't hear her correctly. I look out the window, and sure enough, the little boy is peeing in our grassy area ON THE SIDEWALK IN FRONT OF OUR RESTAURANT! When he finished, she just brought him back in and went back to whatever she was doing.

wtf??

I guess if that is the only way to keep your child from soiling himself, more power to you, but wouldn't it have been better to at least try to get out by the parking lot or something? Very strange.

By the way, the restaurant is in Brentwood, so you would think the patrons would be a little more classy...
