Some more either "A" young, untenured reps, or you were born and raised to be afraid of your own shadows. "I'm afraid of my DM" "He/she may yell at me, put me in a corner in the doctors office, or make me write a essay." "How many signatures do I need?"
If you have to ask a question such as that, then you deserve everything that you get. How about this - Try just going to see physicians to speak to them. If you don't get samples out for a fucking signature then so what! When your DM asks why you have only 1-2 signatures maybe, tell them that's because you are doing your job like an adult.
