I have both problems, actually, long legs so the knees take it, and then the back.  So I sympathize.  But I won&#x27;t call the person in front &quot;rude&quot; and the person behind &quot;right&quot;.  And I certainly wouldn&#x27;t presume to judge whether the person in front &quot;doesn&#x27;t deserve&quot; the space based on, say, them being 5&#x27;.  You could just as easily call the person in back rude for having the temerity to have long knees poking into the seat back.
