Horrible food

Went to Mcdonalds with my sister last night and we ordered two foldovers and chicken tenders but when the food came, the chips had a funny smell but we thought we were imagining things or maybe we are too hungry but we ate, we did not sleep we had and still have diarrhea, its the worst mcdonalds we've been to, their service is not nice at all.

About two weeks ago we had gone to the same McDonalds and our food took 20 minutes to be prepared, finally when our food arrived, i asked the lady for a tray as we had decided to sit down and eat and she told me i didn't specify on the self service machine that i need a tray, when another lady asked for a tray she was told all trays are dirty
