I was walking by a dry cleaner at 3 a.m., and it said "Sorry, we're
       closed." You don't have to be sorry. It's 3 a.m., and you're a dry
       cleaner. It would be ridiculous for me to expect you to be open. I'm
       not gonna walk by at ten a.m. and say, "Hey, I walked by at three, you
       guys were closed. Someone owes me an apology. This jacket would be
       halfway done!"
