What settings have you found where you could call yourself "doctor" without someone mistakenly believing you are an MD? The only ones I've found so far are in academia and at work, but in both cases it's not really that much of a boost. (At work everyone more or less has a PhD.)

The pub.

"Hey baby, I'm a doctor. I do radiology." (Both true statements.)

"Ooh, tell me more."

Yeah, mainly the pub, but also any situation where you want someone to do something that seems risky:

"Trust me, I'm a doctor!"

And dealing with unhelpful customer service:

"We're sorry Mr Smith but we can't do that..."

"Actually that's DOCTOR Smith"

It won't help you get what you want, but the amusement factor will make you feel better.

A friend of mine has Dr on all of his credit cards. He claims to have received free upgrades on rental cars from time to time as a result. Not sure if I believe that.
