McDonalds

Today I went to McCafe for a drink and ordered a Fluffy. I paid and sit down as the staff will bring it to me. A few minutes later, a guy brought the drink to me and said that need to get additional 65 cents due to the extra vanilla. I was sort of confuse and paid up. After that I still dunno what it means and check with my friend. I think that guy made a mistake and ask me for the money cos I never ak for any extra vanilla. I should have argued with him at that time. Now realised a bit too late. Any way, I shoot one letter to McDonalds for clarification. For now I will boycott McDonalds.
