Here's a kind of slaggy one:

 

Bags:

Where are those carrier bags?

No, not those recycled poncy type.

The slaggy ones, a slip of plastic, 

with Key Markets or Tesco on the side,

Like me Mum had.

 

Throw away ones - which is exactly

what you did.  

Shamelessly, without a single qualm. 

plenty more where they came from.

 

Don't get me wrong, I salute those 

tasteful bags for life, and the five

pee charge. 

But they're boring!  And virtuous.

I long for those unlovely rolls of pitifully

thin bags,

that took a piece of me with them.
