This is a very big issue for me. My wife and I usualy split a dish. This is for several reasons. One, to keep our calories at bay. Two, to save. Three, we fill it is a closer experience when you’re sharing. We do not drink (at restaurants anyway), and very rarely get dessert. We usualy go out with friends, since we love the company. But sometimes they will want to split the bill after some had drinks and/or dessert, not to mention the lobster tortellinis. On top of that sometimes, out of “carelessness” they would even count us as two, even though we consumed as one.
It got to be so ridiculous that one night everybody got lobster, since everybody thought “If I’m paying for his and her lobster, I’m getting me lobster too”.
After that I opened the conversation. Some people didn’t like it (Surprise!).
But now it is much better, you ordered it, you pay, unless we are at some asian place where you eat family style (but that’s not usual).
