Canon Mills Newsagent in Edinburgh

I went in to try to top off my bus pass and was told there was a £1 fee. I asked if this was legal and expressed concern (spoiler alert it's not legal for them to do this). The woman got angry with me for asking and was very aggressive. I tried to get her to put the money on the card anyway (I needed money on my bus pass and was late for a medical appointment) but she refused and was aggressively belligerent, telling me to get out of her store or she'd call the police. I have reported them to Trading Standards as these actions were illegal but want to spread the word that this is how they treat people.
