McDonald's Served Me a Drink with a Plastic Cap Inside

Today, I visited the McDonald's located on Karanfil Street in Kızılay, Ankara, Turkey. The drink I purchased had a plastic cap inside, which was absolutely unacceptable. I have been eating at this restaurant for many years, but I have never encountered such a disgraceful situation. This raises serious concerns about the hygiene and quality standards at this branch. What if this had caused a health issue for me or someone else? Such carelessness is not acceptable from a brand like McDonald's, which is known worldwide. I am requesting an urgent response regarding this issue and expect compensation for these products. Immediate action should be taken to prevent this from happening again.
