When I was in high school in 1991, some friends and I went to a Denny's restaruant in San Jose, Ca on Blossom Hill Road after a college recruitment seminar. When we walked up to the hostest, we were all told that we would have to pre-pay a 5 dollar sitting fee. We were told that this was a new policy of the company. We paid and were seated. We were seated next to a table of some of our white friends from school. We asked if they had to pay a cover charge to sit, and they said no. Long story short, that was the beginning of investigation of Denny's discriminatory practices. My personal experience was reported in the New York Times, where my classmate was quoted.

That same year, my parents stopped at a Denny's in Truckee, Ca on their way to Lake Tahoe or Reno (can't really remember). Anyway, another long story short, they were never seated despite the fact that other customers who arrived way after them were seated.

Those are just some of my personal experiences about discrimination at a well known business establishment.
