This was suggested to me by a friend.
I give, I take
Not known to make a mistake
Like it or not, I call the shots
To complete your task,
Questions I must ask.
For a start, prove who you are
Or you won't go far
Options I set and choices you select
What do you want? Come on, answer my prompts!
A bad selection, and you'll suffer a rejection
Hey, don't get edgy
If you want to achieve your goal early
Everything is cool
If you bend to my rules
Look, you have just finished
Will you take that small sheet?
Someday, who knows when
We'll meet and do it again
Who am I?
