I have a good mechanic. A bunch of locals discovered we have a good mechanic in the neighborhood, and the guy got too much work and had to stop taking new customers. As an old customer he still works on my vehicles, after a month or so on his schedule. So for this one small business I'm a legacy admission. So say I call him up as a new customer. Scenario 1: Sorry, we can't take new customers, we're full up. Scenario 2: Sorry, we don't accept customers of your race/ethnicity/religion/sexual-orientation. These scenarios feel very different to me.
