Mostly non-adult, as honorable employee has only thirty minutes to make delivery. Not enough time for proper foreplay and decent servicing of client.
Also, Ninja Burger Employees do not exist. Ninja must take great pains not to be noticed. Giving client a massage would be most noticeable!
In spite of the system, this game tends to be rather fluid...but straightforward. The Ninja Burger Employees get a destination, a client, an order to deliver, and how much time they have remaining to get order to customer. Where they go from there is up to them.
Oh, there's a random complication table, to be sure...
