Then again, when the little sign in the handle says "occupied" at the local truck stop, I intentionally use the lady's room. Practical I am. If they complain I can just tell them "OK., I'll go out by the front door and pee in a bush?"
Or you can use the line I did when I mistakenly went into the ladies room once. An older lady got all huffy and said "sir, this is for ladies only!!"
My reply: " So is this but right now I've really got to drain it."
Quick wit. That's the kind of line I can only think of after.
