Models need to have a Tip Menu set up. The Tip Menu items help with achieving the current goal, like getting naked, for example. The Tip Menu contains a Token price and what the model will do. eg. 35 Tokens to ass flash.
To make Tip Menus I like to use the Tip Menu Plus20 bot (up to 20 items)
The format for setting up the items is Token Price Dash Dash Item eg 10--PM
