*****, *****, *****! You'd ***** if they hung you with a new rope.
I don't mind if people open doors for me, even if it's not necessary. Getting anyone to say sir these days is a miracle. You have young girls saying it and you're complaining? AARP is not exactly flooding my mail box, but until recently, the junk they did send had a handy postage-paid envelope in which I was pleased to return said junk, torn into a more or less appropriate number of parts. And although I seldom forget why I went into the kitchen, I can almost always figure out something to do once I find myself there.
You should certainly feel free to be grumpy, particularly if you enjoy it, but there are alternatives.
