Today I went to the graphic centre in covent garden, after I got home I checked my recipt to find I had been charged for additional items that I hadn't even taken up to be scanned, I went back to the shop, wasting time and money on travel.
Not really happy with my experience today, perhaps staff should be more careful what they scan.
Not sure if I'll be going back to be honest.
