I hate McDonalds, they nearly killed me. When i was six years old i was allergic to many things, including milk and glutein. So then we here that there is a glutein-free hamburger, which doesn't contain any milk. My parents phoned McDonalds and asked them and they assured us that it was milk free. So we went to a McDonalds and there we got the same answer. So I took the hamburger and ate most of it. We left the place and 5 minutes later I was in an ambulance and in an anaflactic shock ( Anaflactic shock is a severe allergic reaction. You get spots all over your skin and tickles like hell, your blood pressure drops dramatically so that you're at risk of getting a heart attack and if that isn't enough, your neck starts to swell up from the inside and blocks your airway).
So afterwards my parents phoned the place and again they told us it was milk free. Later on they realised that there was milk in the bread. They were so sorry about the whole thing that they gave me a few coupons to foods that I couldn't even eat!
Thx Ronald!
