"When ordering menus I usually take frappe as a drink. It came to my attention that despite regular (medium), the drinks weights quite easy, definitely not 400g, as stated on the bill, as well as what McDonalds website says. So I checked the weight at home and found out that together with the cup drink weights 320g. Today I ordered the same menu as usual, frappe was once more bright. He asked McDonald's staff to weight it for me, first he refused, but in the end he brought scale. He was very confident until the weight balance showed 325g. He filled up to 400g without a word. I'm sorry, nothing. Then he continues to discuss with colleagues with disregarding me that I dared to question the service. What's wrong with McDonald?"
