I was shopping in a UK high street supermarket and at the counter I tried to purchase a lottery ticket. The person serving me asked me to remove my mask. I explained to them that I would prefer not to and I gave them my ID which they looked at and I told them why I would prefer not to remove my mask. The person then got really angry and demanded I remove my mask, I told them they were making me really upset and against my wishes I removed my mask. At this point they looked at the people in the queue behind me and shouted 'My dad has xxxx as well and your upsetting me!' At this point I was shocked and tears started to well. They then turned to a colleague and told them to serve me because they wouldn't. I was so upset I rushed out the shop without buying what I had wanted. I contacted their customer service via email and after a week of looking in to it they have apologised and said they have dealt with the staff member concerned. My question is this - would it be wrong to expect more than an email apologising? I am utterly devasted by the way I was humiliated in front of all those people and I am no longer able to shop in that store because of the way I was treated and made to feel.
