Not principally, no. And I also don't take coffee breaks while navigating through the mail slot.So, you propel your ship principally using your ventral thrusters?
Personally, I think that putting your argument forward should disqualify you as a pilot because you are obviously a hazard to navigation and likely to get your ship stuck in the mail slot on a regular basis.
But for the occasional espresso in deep space, it's easier than finding a landable moon with a nice view.
Besides - my ships fit through the mailslot in any orientation. That thing is, after all, more than 50 meters high.
