It's basically setting up Gates as an amiable ol' fellow, the everyman, he shops at a discount shoe store just like the mexicans...!?!!!!![]()
I found it odd that the people in the window happened to be Latin Americans, Seinfeld just happened to be eating a churro which is a pastry popular in Latin America, South America, & Spain, and the shoe just happened to be named The Conquistador, which were the Spanish Soldier/Explorers who 'found' South America & claimed it for Spain. But for some reason, Jerry Seinfeld and Bill Gates aren't on their radar, they're only concerned with The Conquistador.
