I want your opinion on something

I want your opinion on something My partner and I had an idea, and I finally agreed to try it. I had to call a drugstore while she was nearby and ask if they had a specific medicine. Out of 12 calls to different places, I was only able to actually say “hi” and ask about it on the fourth one. For the rest of them, I just stayed silent while trying to say something, listening to the other side say “hello?... hello?” before hanging up. Do you think that’s actually a good exercise to help break barriers? I guess I'll try again tomorrow with a different place and subject.
