I’ve noticed that ground crew do not do there jobs for too long. I have a fix that I have been thinking about, what if you could select how long you would like the ground services to do there job for. If you were in a hurry, you could select a short amount of time. If you want a realistic experience, you could select a longer amount of time. This would apply to only fuel, catering, and baggage.
Let me add this is not a third party mod I am just simply requesting this feature to be added later on.
