Poor servicev

I was at Mc Donald's Brits Mall on Saturday and can assure that the service was by far the worst experience I have had at a Mc Donald's. The staff was extremely unhelpful and the laziness to take my order at till point was alarming. A staff also could not manage placing my order as she herself did not know how the kiosk work. I wanted to buy the cheese fries and was told that I must purchase it through the app which at that time I did not have. I offered to buy it over the counter but was told I cannot buy over the counter. This is ludicrous and insane. Mc Donald's Brits Mall has put me off Mc Donald's going fowrd. We were 4 people wanting to place one order but was not assisted. What a pity 4 people had a bad experience.
