Good day :) , i'm a programmer myself. I've been working in a company A for almost 1 and half years by now. I'm not sure this has been confronted by anyone of you but i find it quite.. annoying.

It happened to me when a colleague that same team as me who sit next to me , asking for confirmation. But then right after i finished explaining how things are done and work. He then again ask other colleague the same question to other team member in front of me.

It makes me feel like, he didn't trust me and i din't give enough information etc.. How did you overcome such situation?

There is a specific team member on my team that comes for me to clarify his questions. Once these questions are clarified, he does the same questions to other team members.

What would be the best approach to make sure the information provided is enough and to let him know that if the information is not enough he needs to state it instead of going to another team member and ask the same questions all over again, wasting both my and my team mate's time.
