Asking if I have time for something unimportant is as inconsiderate as just saying 'hi' imho. I will still have to remember to call them back (so their problem is now a task more for me to remember) and I'll still have to consider if it isn't important after all to ping them immediately. Because maybe last time they pulled the same stunt with a major problem and I initially got chewed up for doing minor stuff instead of asking about theirs... So imho: either state the problem in a concise way and state your priority evaluation. I may adjust that evaluation based on my interpretation. Or just don't bother me with it because it isn't important.
