What social blunders does Eliza commit?

Eliza Doolittle, in George Bernard Shaw's "Pygmalion," commits several social blunders primarily due to her lack of refinement and understanding of upper-class etiquette. For example, she often uses improper language and expressions, which embarrass her when she interacts with high society. Additionally, her frankness and lack of awareness about social norms lead to awkward situations, such as her unfiltered comments about wealth and class. These blunders highlight the challenges of social mobility and the superficiality of social status.
