I dont even ask people questions anymore. I'm tired of the sneer and the "Did you ask Claude?" responses. I had a manager say "I'm here to help in any way I can", and then every way I brought up was "We expect a Senior to be able to answer that themselves" or "Did you ask claude"... thanks for the help, so much for teamwork.
Turning people down when they ask questions is such a short-sighted perspective. When you answer, you can tailor it to them, you can give extra context, you can elaborate, you can dive into specific nuances. Long-term it will be very likely a positive thing as the person will trust you more, they will be comfortable asking more questions and the knowledge might actually help them to contribute in the future.
