lmao! @Meesterboom today you're sounding like they all want to kill you in your work place. Well the world is evil these days and such one has to be extremely careful in their dealings with colleagues you have had a fight or exchanged words with at the office, they may not mean well. I would just say you are being careful regardless of whether it was poisoned or not.

Well i have also had such experience but not at work place at me apartment and it was neighbor who we don't move on well with but will always bring food for me to eat and once i collect i pour them imside the toilet and then return the plates neat and with a smile on my face, ah madam your food taste delicious just to turn her mind away.
