What is with this self service nonsense these days, I always end up in a state. I was sent to get some bits and once I was paying I was in a cue of basket carriers. So with four self checkouts going at once I was poised and ready to pounce.
I saw my chance and leapt into action. I was aware of the people behind in the queue would now be watching me to do the deed smoothly so they could do theirs.
I scanned my goods and the machine said "select payment"
It even went as far as saying "put your card in the machine..." I stopped listening as a carrier bag  had been tied around the card device. The helper leaned in and tapped a thin yellow plastic strip along the top of checkout which read 'cash payment only'
So I was flustered and was sent to the cash machine. I always end up in these situations and instinct always tells me to just drop my goods and run (not joking).
But I kept as cool as possible and sauntered back to my position with a tenner, which put everything to rights.
Having returned home my wife said I had bought the wrong sort of sauce and so I returned to supermarket but this time more prepared. This time I was not going to the cash only position and was being mumbled and glared at by the people behind who also did not realise his was an odd one out position. I don't get my shopping any cheaper for doing it all myself and the cue is just as long so I don't see what the benefits are.
