How would you deal with an Eastern European (?) immigrant being casually racist?

The woman who waxes my legs was wittering on about how dreadful the Councils are and how stupid they were to house a family of Gypsies in a big house - "because you know what they're like" - I'm not sure where she's from, but doesn't it seem a little off?

Your thoughts?
Update: Lopez - thank you for understanding my predicament - I really don't want to rile a woman holding hot wax over my bikini line!
Update 2: Thanks for the advice meganjess - unfortunately I'd just paid for treatments in advance to get the discount!
Update 3: Hatters - what a wonderfully positive spin - are you in government?
