I agree, to give them 2-3 chances and allow you to know them. She may had bad day herself and was being to "snappy" or short with you...or she may be strict and that causes you to say eeewww! no way....prepare, write some questions down and ask them to see how you feel with them.
Some pdoc may be more gentle, some more stern...they just need to be helping YOU!
good luck
