- WSWahid ShaikhAug 6, 20265.0I had a wonderful experience at McDonald’s thanks to Shakeela. She was incredibly friendly, welcoming, and professional from the moment I arrived. She made sure my order was correct, served everything with a smile, and provided excellent customer service throughout. It’s always nice to be served by someone who genuinely cares about customers. Thank you, Shakeela, for making my visit so enjoyable. Keep up the fantastic work!
- ATAlfie TaylorAug 2, 20265.0I would like to thank the security guard, who I believe was called Ben, for being so professional and helpful. He was extremely professional throughout and made sure we felt safe and looked after. We were stuck in Cardiff with no way to charge my phone, and he kindly went out of his way to help us. Thanks to him, we managed to get home safely. A top man and a real credit to the team.
