A Short Change is someone who steals small amounts of currency during monetary transactions. This is achieved by giving less change to a customer than what they are owed.
Short Changes look almost exactly like Cold Callers. The only main difference is that the Cold Caller is a Sellbot and has a darker tint of blue, while the Short Change has a lighter shade and is a Cashbot.
Short Changes have the most powerful version of Pick Pocket, dealing 6 damage at only level 5, which is much more than the other cogs using the attack.
Short Change promotion requirements are the same as Telemarketer promotions.
Short Changes are the strongest cogs at the bottom of the cog corporate ladder, because their Bounce Check can do a maximum of 11 damage.
A Short Change hitting a Toon with Bounce Check at Level 5 actually does more damage than a Level 11 Corporate Raider hitting a Toon with Canned, as a Level 11 Corporate Raider using Canned only deals 10 damage.
