E. coli takes closer to 48 hours, a pink burger is not what you got your illness from.
I just don't think it's fair to blame Shark here on a public forum for an illness you claim to be their fault, when the evidence does not even come close to matching.
Seafood could have E. coli (same time span), or other issues.
You seem to get sick a lot after eating at restaurants, you also might have a weakened immune system in some way.
I wouldn't call getting food poisoning twice in my lifetime as proof I have a weakened immune system.
And what you have done is taken just one of the disease causing organisms and automatically applied it to my case as some method of disproving my assertion that my food poisoning was caused by the burger. There are dozens of disease causing organisms that could have resulted in food poisoning within that timeframe.
I don't have a problem with Shark Club, and even the best restaurant can have a food poisoning case if an employee makes one small mistake. I was merely sharing what my experience was.
