Is it vegan if...

You've been there...standing in line waiting to order food.  You review the menu, nothing sounds good.  Most of you would leave or suck it up and order a burger.  This is somewhat of a challenge if you live in Spokane, Washington and you are vegan. For me, I am an optimistic about Spokane.  I think restaurants are coming around.  They may or may not have tofu.  They always substitute the meat or protein with mushrooms...by the way I DESPISE FUNGI.  And, when you say vegan, they instantly think vegetarian so they mix the salad in bleu cheese dressing or pieces of Parmesan.  Just a bit of educational advice, vegan is described as "no dairy - that includes cheese and eggs."
Recently, my friend and I had a hankering for breakfast at lunch. We stopped by Maggies (nice people but they need a bit of education).  My friend, by the way, is a big carnivore - hint, he eats items with eyes and parents.
We walk up to order our food, they didn't have egg substitute or anything vegan/vegetarian on the menu so I actually ordered something for lunch rather than breakfast.  I ordered their Thai chicken salad minus chicken.  So, for those of you who haven't been to Maggies, that is peanut sauce dressing, lettuce, tomatoes and chicken. The chef's had a difficult challenge on their hands...don't add chicken.
You can imagine my surprise when I over heard the chef say, "oh, this one didn't want chicken - wait, OK...pause...now what I am going to do?"
Five minutes later, we got our food delivered to our table.  Delightful presentation.  Again, nice people. I took my first bite, pretty good.  I looked down, there it was a piece of white chicken breast...at this point, I pass it across the table to my friend's plate.  I thought one piece...it's fine.  I took a couple more bites, huh, there's another piece.  Again, I pass it across the table.  I wondered at the particular moment in time...is this really a vegan salad.  I'll be honest, I was hungry.  I ate the rest of it but still.  Is it vegan if...the restaurant doesn't know that chicken is a meat and by taking it off the top of a salad or picking it out of something is really not taking the time to get to know what a vegan/vegetarian guest eats.
