I ask, you reply.
The more succinct the answer, the better.
The more accurate, the better.
However, just make sure the succinct answer is accurate.
Unlike this guy.
Too Short: I have this refill to drop off.
CP: When did you want to pick it up?
TS: She needs it. (actual response)
With such an open-ended answer, Super Intern and I decided we needed to work out our responses.
"She needs it..."
1. So, when?
2. I can see that from the empty bottle.
3. I'd love to give it to her, but she's your wife.
4. Okay. Go home and give it to her. By the time you finish and get back, the prescription will be ready.
See what happens when you don't say "I'd like to wait for it"?
