Sandwich surprise

Gather up
The usual faces
Have them stand
In the usual places
Looking for something
Inspiration, may be
Or just a change
From normality
They'll shuffle around
But it remains the same
This lunchtime ritual
Seems a desperate game
What's provided is all
The usual fayre
Do they choose from desire
Or out of despair
But shuffle they do
And peruse the same shelves
In a small crowd
But alone, by themselves
No matter their search
It's all in vain
No miracle here
Just the staid and the plain
They take their pick
And leave in sorrow
And you'll find them
Standing there tomorrow
in their Sainsbury's Local
Or Tesco Express
Why don't you just make
Your own sandwiches, yes?
