I looked at the poster after the controversy started, so I can't say I looked at it objectively. But it DID remind me of September 11, in an eerie way. Just a coincidence, I think.
As for Starbucks, I occasionally have a sit down and a coffee there; it's right across from my favorite music store--the Ottawa Folklore Centre! and the coffee (basic) is a buck-50 canadian, close enough to regular prices...
...and sometimes I do shop at Walmart's...
