With that Negro now
I don't pay no REVERSED
CHARGES nohow
You say, I will pay it--
Else you'll take out my phone?
You better let
My phone alone
I didn't ask him
To telephone me
Roscoe knows darn well
LONG DISTANCE
Ain't free
If I ever catch him
Lawd, have pity!
Calling me up
From Kansas City
Just to say he loves me!
I knowed that was so
Why didn't he tell me some'n
Madam Johnson is upset because Roscoe is calling long distance from  Kansas City , which costs more than a local phone call. Apparently KC is far away from where she lives.
