The Pepsi representative and the people at the advertising company were satisfied with the photos and with Jake's work that day, they had already worked with other artists who were much more annoying and had a lot of demands.
Jake did everything the director of the commercial told and worked for hours without complaining once and also did not make mistakes in the commercials, David was also happy with that because Jake was building a good reputation among advertising companies and among sponsors.
These companies that sponsored Jake were big companies in the market that wasn't even spending a lot of money on that sponsorship, so if they liked Jake and if they realized that the public was buying more of their product because of Jake they could renew the contracts throughout Jake's career and paying a lot more.
