Yes, it is generally considered inappropriate and creepy for someone to ask about their date's salary or financial information early on in a relationship or before going on a second date. Money matters are personal and sensitive topics, and discussing them too early in a relationship can make the other person feel uncomfortable or even judged.
Asking about salary can be seen as intrusive and may give the impression that the person is primarily interested in their date's financial status rather than getting to know them as a person. It's essential to respect boundaries and focus on building a genuine connection based on shared interests, values, and emotional compatibility.
If financial matters become relevant to the relationship later on, they can be discussed in a respectful and considerate manner when both parties are comfortable sharing such information. However, during the early stages of dating, it's generally best to focus on getting to know each other's personalities and interests rather than diving into potentially sensitive topics like income.
