I am regular tea drinker. So one day I go to the kitchen, take a tea bag, remove the cover of the bag, put th cover in the cup, throw the actual bag containing tea in the garbage, pour water into the cup and drink it. It did taste a little different, but as I drink tea without sugar and milk it didn't somehow matter. I did not know until I finished drinking. I peeled an orange threw the orange away and almost started munching the peels before it was too late.
