With the phone, I pretended to make calls and receive calls before I applied it to a real time scenario. Plus, you can download soundclips of noisy restaurants and just practice at home. I practiced for months and months until I applied it to real life situations. When it came.time to call or order, it just came naturally because I had practiced all those months until it became boring. Practice DOESN'T make perfect,I don't believe in perfection. Practice makes PERMANENT.
