<<I have no need to look into the standards on meat grading.  I'm only
asking that you substantiate your assertion about the quality of meat
that is used by the major burger chains.  Somehow, I'm not surprised that
you are not prepared to support your statement...>>

Wally,

.  What you seem to be missing is that I have no personal need to prove
this.  I was merely sharing info.  If someone is interested, they can pursue
it themselves.  Is it only I who evokes this rudeness in you?  My life is
not spent online providing documentation for everything I say.  How about if
you are so interested, you DISprove it.
