Do you want a bag?

"Do you want a bag." asked the bored lad at the COOP checkout.
"No thank you.", I replied.

I should have said, "No thank you you fucking stupid cunt!!!I will put the bastard loaf and two litre container of milk in my pockets the net of fucking onions on my head and balance the fucking jar of bovril on my fucking NOSE!!!"

But I just said, yes please...
