This insanity has gone on entirely too long.
"their" is plural
"Is" is singular
ergo this thread should be titled correctly
"Are there people you wont buy from simply because of their attitude?"
Everyone knows that there is more than one person out there with an attitude.
Also an acceptable alternative
"Is there a person you wont buy from simply because of his/her attitude?"
This is for folks who don't recognize an attitude when they see one.
