Digimon Adventures 01
A Digitamamon was first seen running a diner with Vegiemon who forced Joe and Gomamon work off their bills, due to the fact that he only accepts Digi-Dollars. Joe did have Digi-Dollars on him but was stolen. Matt arrives to help Joe work off his bill and to ensure the safety of Joe when Digitamamon made a threat about "accidents" after DemiDevimon paid him in dollars to keep Matt at his dinner.
DemiDevimon told Matt that Joe was deliberately causing accidents so Matt would stay there forever. Matt eventually blew up and yelled at Joe. However, when Tai, Agumon, T.K. and Patamon found them, Matt decides to leave. Digitamamon, knowing he'll lose money, grew large and attacked. Vegiemon grabbed T.K. and held him by his ankle; Joe daringly jumps on Veggiemon, which freed T.K. and proved his reliability. Matt was stunned at how Joe tried to protect T.K. even after he yelled at him. Matt's thought of friendship allowed Garurumon to Digivolve to WereGarurumon and defeated Digitamamon, sending him flying.

Everyone, except a still-annoyed Yolei, believed he was telling the truth.
