On a recent trip after departure tower cleared me to climb and contact terminal. This is how it went ( note it was a not very busy mid week afternoon)
Me: XX terminal Grumman AA1 ABCD
Terminal: Hi (my first name), Yah going to XX
Me: Yup, five point five please
Terminal: BCD cleared to XX at Five thousand Five hundred
Like it.
