The counter personnel, including shift managers at the McDonalds that I visit have a "bad" habit of speaking Spanish to the employees in the kitchen area. Not only is it rude to do this in front of the customers, but there are also non-Spanish employees present. There are several McDonalds locations that have this "bad habit"
If McD insists in hiring employees who do not speak English, they should send them to an English class.
Last time I checked, this was the U.S.A. and our language is English.
Learn it, I did!!! It amazes me that people want to live and work here, but refuse to speak the language!!
