Saw this in my local paper today, under the section where people try and get issues solved, when they haven't gotten anywhere themselves.
BG: Couple says they recently embraced a vegan lifestyle and diet, for health reasons. But said their new dietary choices make it challenging to eat out, so they had taken to bringing their own pasta to restaurants, and asking the chef to cook it for them. He went on to say a few times since they broght their own, their bill was discounted. Which he also said they didn't ask for, but was nice of them to do. He said they've been to 50-60 restaurants in teh past year which have had no problem accomodating their requests, and said "To make it easier for servers and chefs, the _____ took to writing their dietary needs and cooking instructions on cards, which are handed in when they place an order."
The problem occured when they were out, and were charged full price for pasta entrees, even though they provided their own pasta. He said they had been to the restaurant in question previously, and were only charged $12, but this time were charged $24. They were told it was beacuse the last time it was a different manager. They went on to dispute the charge with Am Ex, over $12 - the difference he thought they should have been cahrged, and what they actually were.

but aside from the fact I'm surprised that any restaurant would cook something a patron brought in, they seem to be a bit snowflakey to me. If eating out is such a challenge, then perhaps they should start cooking at home. And to make such a fuss over $12 is a bit over the top, IMHO. Then again, if I had any major dietary restrictions I'd either avoid eating out, or make the best of things, but I would never ask a restaurant to cook something I brought from home!
