...and I'll echo what the other's said--Check your order before you leave the restaurant!
I'm not sure where your from so maybe Red Lobster is the best Seafood place in your neck of the woods, but I, for one, do not consider the food at Red Lobster to be of good quality. I guess I'm spoiled, in that I live right on the coast and quality seafood is not hard to find. I only go to Red Lobster once in a blue moon for their endless shrimp special.
Flounder is considered safe for pregnant women but I believe there is still small levels of mercury in it. I'd like to know why you drove 35 minutes to get take-out food? And even if the restaurant screwed up the order, I don't think you should be compensated for time and gas because even if the order was correct, the drive & gas used would of been the same.
