Racial profiling isn't the only problem with retail.  A friend of my parents went into an Ottawa Ben Burk Jewelers store to buy a wedding gift.  She was dressed plainly and the sales clerk refused service and told her she couldn't afford their products.  When she arrived in Montreal she called her Uncle Ben to inform him of her experience.

My cousin's father-in-law went to a local Chev dealer and saw a Caddy he was interested in.  The young salesman attempted to direct him to a smaller, cheaper chev.  He left.  An older salesman found out the customers name, and drove that Cadillac to the farm and sold it on the spot.

Do not judge a book by it's cover, particularly applies to retail.
