The guy started D&D camp this week. Yesterday, his party pickpocketed people and tried to cheat at gambling games in a tavern. They did not make it to a dungeon.
This is legit D&D! You can do anything you want*!
However, I am tempted to role-play the Concerned Parent and complain that he's not getting his Dungeon Time in!
*Depending on DM mental tiredness.
