To think you shouldn't advertise where you work and then call customers chavs?

I saw a comment saying they worked for a designer store and find it hilarious when chavs come in and are told not to wear fake tan with the watches they buy.

Aibu to think this is wrong?

YANBU. Some people are unthinking idiots on social media.
Did they say in their profile where they worked? If so they're an even bigger one!
