The answer to the “special Japanese restaurants” question:
But first let me thank those who posted their interesting answers, thank you my friends.
Now my answer to the question:
In the [girl on her back] service, the more expensive one, the chef fills the girl navel with shrimp-cocktail’s sauce and sets a circle of cold boiled shrimps around the pretty little sauce cup, the sauce is a tasty mixture of catch-up mayonnaise mustard and hot sauce.
When the girl lies on her belly the chef sets one pretty circle of shrimps on each buttock, like two Roman victory crowns on each lobe, and naturally the navel is replaced with another hole. In this position the girl cannot stay motionless as she is supposed to, and makes life miserable for those costumers who try to dip their shrimps; so the service is poorer, so it’s cheaper. Because the poor girl trembles all the time with all that mustard and hot sauce in her ass hole.
