Sorry this is long. Was in a (chain) pizza takeaway and witnessed this. Customer probably in her sixties came in with an assistance dog, clearly wearing identification as such. Dog extremely well behaved. Didn’t hear her give it any commands, it never took it eyes off her, sat when she stopped, was glued to her side when she moved. It obviously was well trained and knew its role. She ordered from the young lad and stood at counter. Then an employee approached and she quite aggressively said dogs weren’t allowed. Customer answered it’s an assistance dog. Employee said it’s not allowed. Customer said under the equalities act 2010, the dog is classed as an auxiliary aid, and offered proof. Employee declined proof and moved away. Then about two mins later employee came back and said seen as you think you’re allowed in here can you move over there. Customer said sure and moved. She sat on a bench, dog immediately sat beside her. Employee then came out into the shop and started shouting at the customer and told her that she was being offensive by coming into the shop, and wasn’t allowed. Customer kept her composure and said I don’t know why you’re shouting at me, employee said because of the dog. Customer said I only have the dog because of my disability, so you’re shouting because I’m disabled. Employee then said you’re not effing disabled. Customer replied thank you I’ll take that as a compliment, it taken me 5 years to learn to walk after spinal injury, and are you aware that neurological disabilities aren’t visible. Employee was very intimidating and kept shouting at her to leave, customer refused. Who was BU , the employee for shouting or the customer for not leaving when asked. To be honest I was so impressed by dogs behaviour and how the customer kept her cool. Customer collected her order thanked the young lad for being polite and left. I did see her wiping her eyes as she passed the window. It was all very unpleasant and unnecessary. Imagine being treated like that just trying to buy a pizza.
