File under "cultural sensitivity training candidate #152"

Lynn's Nails is a little nail salon located near my office. I was doing some local searches on Google Maps and found their website. On the website Lynn has published this jem of a culturally sensitive email, apparently from a former customer:

Hi Fawn, I have been coming to your place for a long time now for pedicure,wax and manicures.While I find the services good , there is one concern. When a customer is in your shop,it is rude if you speak in any language among yourselves - other than english.Many of my coworkers/friends have stopped going to your salon as they find it uncomfortable when you talk among yourselves in mongolise/chinese/asian language and laugh. It would be a great idea to make a rule in your salon - not to speak any language other than english when a customer is around. I thought you should know.

Three things are really funny and/or strange to me: 1) what is "mongolise"? and 2) this woman is really insecure and 2) why in God's name would you publish this customer letter on your website when it's so uniformly negative?
