Depending on how the interaction plays out, there is a chance that prejudice would be reduced due to contact hypothesis, but it seems unlikely that the criteria would be met for most services. For some services like wedding photography, however, it seems likely that the criteria would be met and prejudice might be reduced.

I wouldn't think the contact hypothesis would play out quite so nicely under duress from the government. People naturally hate being forced into situations they're uncomfortable in, and I could very easily see that frustration being projected onto the individual/s that the person is prejudiced against.

That's true. It's hard to say. I do know that it was thought that forcing schools to not be segregated would cause the contact hypothesis to come into play and reduce prejudice in children. It was a part of Brown vs. Board of Education. That seems to have worked too, but that was for children. They may not have had much prejudice to begin with.
