I needed help with the self service till in aldershot after making a minor error scanning and told the assistant standing there I had scanned the same item more than once by mistake then tried to void them, the way she spoke to me was completely over the top and unprofessional telling me in a raised voice in front of other customers ( you dont touch the void only I touch the void, you dont ever touch the void again you call me next time) all this in a raised voice in front of other customers. Needs to learn how to speak to people properly.
