"Standing in line to order our food, the lady before us was in a wheelchair and obviously severely disabled. The girl serving her couldn't hide her hatred or disgust. She belittled the lady, treated her like an idiot and raised her voic. The tills are...now separated into cash only or card only till. Tills are in banks of till together with serving space betweeen. This particular till group had cash and card till together with the server standing in the middle no indication which till she was using. The lady in from of us was in a wheelchair and clealry severely disabled. The girl serving her couldn't hide her hatred or disgust. Firstly she asked the customer how she was paying when she was holding up a debit card, then she raised her voice to say this is a cash only till, you need to pay cash. When the lady tried to order food, the server said well u usually have to ask for that! Yes, she just has asked for it!. The server continued to treat the customer with open disgust and humiliated her for a couple of minutes. When the lady asked where the disabled toilets were, she was told they re round the corner but you will have to get yourself there. By now I was raging. I offered to take the lady to the toilet door then asked to see the manager. I was told by other staff there had been lots of complaints about this girl-yeah, then why is she still working with the public? I voiced my anger and disgust at the customers' treatment and suggested that the employee should be made to apologise in public to the customer the same way she had berated her in public. I also suggested the manager refund the customers meal money fully. I should not have had to make this suggestion as he should have already had that in hand. We had our meals in silent rage. When I went to the loo, the doors are locked with coded door locks. You need a toilet code off your receipt to use the loo!!!??? What a disgrace. To add insult, when I used the toilet code it didn't work. I was told they don't always work, so an employee let me in. Toilets are essential for every human being. If someone needed the loo urgently you should be embarrassed into having to ask to be let in when your toilet code doesn't work! All in all a disgraceful experience. Think I'll use McDonald's next time!"
