Supermarket Blues

I hate supermarkets
I only go at night,
So that I don't have to fight
Under stale fluorescent light,
For bread and cheese
And milk and beans
And bacon already going green,
Just to find I cannot pay,
Although I could have yesterday,
And the queue behind me thinks it's funny
That I haven't any money,
Pounds just seem to disappear
Where they go ain't exactly clear,
Probably on drugs and beer
And things that I don't really need,
They fill an empty space in me
Until I haven't two pennies
To rub together.
