I’ve always wondered on Star Trek when they have a quick 10 second scene with a very heavily costumed alien or three if they really did all that makeup and stuff for just that one short scene or not. It seems like a huge amount of work.

I know they didn’t film everything in order, but did they maybe film multiple episodes in parallel? Like, maybe get Quark and Morn in costume for a day and film a bunch of bar scenes for different episodes?
