    I highly recommend that they install self-serving kiosks here it would be a much better experience for customers than having to deal with the unprofessional employees who work the register I came in to order a simple meal and the lady working the register was hanging out with her friends and none of them speak English they all speak Spanish and they were attempting to ridicule me all I wanted to do was order some food if you want to have your friends hang out at the register and make fun of people when they are trying to order get another job

    I want to give a shoutout to the McDonald’s employee who helped me. They were extremely friendly, professional, and respectful throughout the whole interaction. They listened carefully to my order, confirmed everything to avoid mistakes, and made sure I received everything I asked for. The service was fast, and the employee kept a positive attitude the entire time, even though the restaurant was busy. Overall, they made my experience smooth and pleasant.
