Final answer:
Salespersons at the dealership engaged in customer profiling by not approaching Fred and Ethel as potential buyers based on their appearance, reflecting prejudice and discrimination influenced by stereotypes and confirmation bias.
Step-by-step explanation:
When Fred and Ethel walked into the Hummer dealership and were not approached by salespersons due to their appearance not matching the stereotype of a typical "Hummer Buyer," the salespersons were engaging in customer profiling.

However, stereotypes and confirmation bias can interfere with such profit-driven motives, resulting in discriminatory practices that prevent businesses from serving a more diverse customer base and potentially hampering their growth and expansion
