I picked up my bottled water, my shredded carrot and watercress sandwiches and my nutty bar thingy and queued up to pay for them.
When I got to the till I put them down and fished around in my pocket for the money. When the assistant had scanned my lunch, the following short conversation took place.
Assistant: Would you like a bag?
Me: Yes please, when I have to carry three things it makes my brain hurt.
Assistant: *Total blank look, and nothing else*
I wasn't trying to be complicated. I was just trying to lighten up the day a bit. Oh well.
