A linguistic irritant XC

Although I appreciate the politeness of the phrase, "at your earliest convenience," I've often felt tempted to test its limits.  (i.e. "No, I didn't pay that bill, fill out that survey, or return your call yet.  I thought I needed eight full hours of sleep first.  You want me to be well-rested, don't you?  Also, although it's only September, I want to shop for Christmas gifts while I'm inspired.  Obviously, that should take precedence over the task you want me to complete.  Also, my cat wants a drink of water from the kitchen sink.  'At my earliest convenience?'  You'd better bring a chair.")
