This is because in the last month there have been three things, nothing major to me. In the past tenish years since I became vegetarian, only a couple of others.
I was in a well-respected French restaurant in Edinburgh with friends who recommended it, the Salade Nicoise with tuna and anchovies was marked as vegetarian. I did ask, but it was apparently vegetarian to them.
A local new Turkish restaurant we visited to support, which clearly labelled every dish as vegetarian or not, served our separately ordered vegetarian and meat starters on the same plate in front of just me.
Husband was at an event meal, the vegetarian option included prawns.
I'm really interested in other experiences/views. I am also well aware that vegetarian food is different in different cultures.
