rude behavior?

Is it rude to question/ask someone how they could afford to send their child to a summer camp (even if the camp did have a higher than usual tuition)? I was totally caught off guard by someone asking me this question today, and really felt like they were being a bit rude, does anyone have thoughts on this topic?

There is already a thread on this in IMHO.

skimama, please don’t start multiple threads on the same topic in different forums. Also, please pay attention to forum descriptions.
