answer:I also don’t usually eat fast food but if you ask me which fast food I would prefer I would say Mac D (what we call the place here), it has different (if not better) taste than most other fast food restaurants. I must say that it’s not wise to conclude that their food might be bad or the cause of your ‘situation’ as many people are who eat there are still up and running, otherwise you’ll soon find that that the business will face boycott in public. There are many factors that may cause the symptomps like what you described. You obviously don’t eat three meals there, your body might have gone (perhaps coincidentally) through certain biological/hormonal stage at day you eat there, you only eat certain food items that has reaction on your body over there, etc. Until you can gather conclusive evidence I’m afraid it’s impossible to blame Mac D for food poisoning.
