I don't know the circumstances behind my food poisoning. It may be someone who left food to thaw. Or something else.
Simple logic tells me it was most probably store-related. If it was a batch manufacturing problem, it would have come to the attention of the authorities as a mass event. Ditto with a refrigeration failure.
A virus takes time to multiply. The effect of voiding from both ends for 12 hours occurred 2 hours after consumption of the food.
I am scrupulous with food, washing my hands every time before handling. I have better hygiene standards than many of your countrymen, judging by my olfactory experience on the London Tube.
People leaving food behind because they have a hissy fit over slow service, or someone pushing in front of them, IMO are petty and childish. It's no surprise you are in their ranks, without any consideration of possible consequences.
Troll someone else.
