I often deke the goalie in warmups, helps me get my hands warmed up. I don't care if a goalie doesn't try to stop it though, though I like it if they do as the practice helps. On teams, one of the goalies I play with likes me doing that to help him warm up, the other will take some and ignore others. In pickup, goalies have no justification in complaining. We don't know your warmup preferences, don't expect us to.
