I want to start working on a personal project (outside of work hours), but I'm very new to the techniques and methods needed. I know my coworker uses a lot of the techniques in his current position, so I would like to ask him for help.
Of course this would happen in both our own time and I would like to offer him some kind of compensation, food or a beer at the least.
Is it considered unprofessional to ask help with a personal project? I spend time with him on the workfloor but never outside of work.
Should I keep this request outside of the workspace or can I ask him about it during work?
