Little Red Hat.....love it! love it! I'm gonna steal that one from you.
Yecab...depending on how big your tatoo is, maybe you could use band-aid to cover it up on the day of your interview. I wouldn't worry about it too much ONCE you've gotten the job and have been flying around....because so many people break the grooming rules anyway. But to limit your chances of getting caught at the interviews...best to cover it all up with something like band-aid.....then when you work for Qantas...just wear the long sleeve shirts.
