Sense Sonnet - Steamer

Cursed

The express line - it better be.
I knew that I was running late.
Only one gal ahead of me.
I shouldn't have too long to wait.
Moments later, my turn came next.
I pulled the items from my cart.
Then for an hour I was hexed.
The speedy checkout fell apart.
The damn cash register got stuck.
The checker was worthless as s**t.
My ice cream melted - what the f**k?
This piss poor place - the hell with it.

Why do they call this line express?
Four letter words thrown out, I guess.
