Field Mushroom Soup?!?

After much ado...
I have a serious problem with Tim Horton's newest flavour of soup; "Field Mushroom Soup". Guess what Tim Hortons? Button, portebello's or porchini mushroom DO NOT GROW IN FIELDS!! They are grown in dark places in compost. There are other types of mushrooms that are grown in fields such as oyster.

It all has to do with what type of fungi the mushroom is. please refer to

If by any chance Tim Hortons chefs are reading this, please remember that the public is not as dumb as you think we are...and can I get some free soup because of your false advertising?

This was a far less exciting rant than I had hoped it would be. I guess I let it fester to long. Sorry Guys.
