Answer:
The answer is A) curt
Explanation:
Personable means having a pleasing appearance or personality, dextrous meaning an expert ability of skills, in accord with your order meaning knowing exactly what you want, and one who easily transitions from table to table meaning she's on top of things. B,C, and D are all good things and A curt is being rude and short with people so the waitress would not be personable if she was curt.
