Last I checked you had to have some ability to get the aircraft on the ground safely to get the job in the first place. I, personally, don't care if you wore a tutu for 9 years before you came into the airlines, but once you're here a level of grooming should be of some importance. I wouldn't know you from Adam, so I don't know how you fly, and neither do the pax so they judge you by your appearance. So when you look like crap cause you "just don't feel like it" you make ALL of us look like crap.
