Four Seasons Las Vegas February 2010:

In the Verandah restaurant over breakfast, a family of four (Mom, Dad, and 2 boys aged around 6 to 8) being brash, loud and crass. Those were the parents -- especially the Mom. Appears that they were staying at the hotel with another family (relatives or friends, unsure, but they were not at breakfast) The kids were well behaved!! Announcing loudly that they were in an Executive Suite to the hostess, the server, etc so that everybody nearby could overhear:

Mom asks younger son if he likes the Executive Suite.
Son replies: "Nope, I like Steve's room better"
Mom retorts: "Yes, sweetie, but Steve's not in an Executive Suite"
Son replies loudly: "Yah, but they've got PlayStation and Steve's Mom and Dad don't make weird noises like you and Dad do!!"

Mom turns red; the whole restaurant is trying not to laugh -- I certainly had difficulties holding in a chuckle....

I was telling my sister you cannot make this s**t up!!
