Disappointing for the following reasons: I was cheated (in my opinion) of £8 by an extremely rude driver: Informed by the driver of the Oxford tube that an open return journey would cost £20. Having a long queue behind me, I apologised to the driver as I could not find my other £10 note (I took an additional 1 min to check my wallet which I already held in my hand) and the irritated driver told me that a single was £14. I got the message - paid up and found a seat, worried I had lost my note. Within 5 min I had located the missing note - safely tucked behind my oyster card and waited patiently for the next stop. I approached the driver to let him know that I had found my note and to ask if he could refund the single and issue me a return ticket? Now I have been on this coach a few times before where I have had to wait until the end of the journey for my change and been absolutely fine with this. I have never had a problem with 'losing' my money before but it's when you find yourself in a situation like this that you can really see what the customer service and staff training is like. The driver had a serious attitude problem and suggested that if I wanted to buy an additional £20 return ticket he could help me, otherwise he could not (mocking me perhaps?) Surely the drivers are able to reverse a transaction and reissue me a return ticket? The drivers reply to this was 'No, my till will be out by £14 so your too late - you bought your ticket 15 minutes ago'. This does not make a lot of sense - a driver should be able to reverse a transaction (what if he had made a mistake?) - I was still on my journey and of course there was time lapsed from the purchase of the single to when I was able to safely speak to the driver i.e. when the coach next stopped. Extremely bad customer service, totally unnecessary and avoidable in my opinion. TAKE MY ADVICE: check for cheap rail tickets - I found several tickets for my single journey back for various times, priced at £4, £5, £10, £11 & upwards to London Paddington (go to nationalrailenquiries or thetrainline.com) If you can be flexible with your time its always worth checking - the journey is more comfortable and a lot quicker.
