I visited the McDonald's next to Boon Keng MRT (S330022) around 10:50 AM today to buy an ice cream for my child. Due to the crowd, I politely asked a tall Malay male staff member in charge if I could be prioritized since I was only ordering one ice cream. His response was a firm "no," delivered in a harsh and unfriendly tone. I complied and waited as instructed. While I understand the need to follow the queue during busy times, I am extremely disappointed by the lack of flexibility. I waited 30 minutes for a single ice cream. Even worse, my order number was already first in line, but the Malay staff member at the counter still ignored it until I reminded her. Her attitude was appalling—she glared at me with hostility when I raised the issue. Additionally, I observed the Malay male supervisor treating other customers differently, which further upset me. His service attitude was unacceptable for a management role—no smile, loud and rigid tone, and zero empathy. In contrast, staff at other McDonald's outlets often check on families with waiting children, especially for simple orders like ice cream. He can ask me why did I ask to get the ice cream first? Then I will let him know my child had just participated in a government-organized performance at the MRT station and was already exhausted and feeling hot. We just wanted to buy an ice cream and leave quickly. But the manager didn’t even bother to ask or understand the situation—he just immediately refused. I believe that, no matter what, he should have at least asked for the reason. That is the most basic level of good service. This was a terrible experience, and I will share this feedback on public platforms to highlight the poor service standards. Urgent staff training is needed to address such unprofessional behavior. Thank you for your attention. Additionally, I would like to know how such complaints are usually handled. At the end, when I asked him for a feedback form, he showed no good attitude at all. He simply responded in an assertive and almost dismissive manner, saying, "You can give feedback through the app," without any sense of professionalism or courtesy. If our feedback has no impact or isn’t taken seriously, then what is the point of having such a system in place?
