From what I can piece together I think she got kicked out of the restaurant for being an asshole, and in kicking her out the management refused her payment for the meal but also made a copy of her ID to post behind the reception area in order to warn the restaurant staff that she was not welcome there in the future.
The guy recording the incident sounds like he just happened to be there when it all went down and the Racist Horrible Person decided that the mere existence of a Black man in Santa Barbara was noteworthy enough to elicit mockery.
Racist Horrible Person mentioned other people being with her who offered to pay for the meal but I guess if she had any companions when she got there they wisely put some distance between themselves and her by the time the recording started.
