Sorry, we no longer accept cheques

I always feel inspired after hearing the other amazing talent this country has to offer.  Written on the way back from the slam final, prompted by the sign at a petrol station pump reading "Sorry, we no longer accept cheques'.

Welcome to the postmodern era
for someone like me it couldn't be clearer
We've technophobes
and nomophobes
and silver surfers
on Google Chrome

I'm telling you, they're all on 1D!

Now we don't even need money to pay
we wave cards at readers with a 'have a nice day',

word for the noughties
or whatever this decade is called
(I vote we leave the numbers thing and just call it 'Paul')

Yes, this is the postmodern era
Already these words the last in a thin, crumbling tier
Defunct
