I think that Mr. Johnson is less sympathetic in this sketch than in some of the others. "See you tomorrow"? WHY? If I were him, I would have cut my losses and gone without the olive...and maybe without the pickle.
Nevertheless, this sketch reminds me of a restaurant in Hill City where my younger brother and I once ate. The service was TERRIBLE. We had to wait what seemed like hours; it probably was close to one hour. Shortly after the waitress brought me my sandwich, she sidled back to me saying, "Um, there was a mistake in the kitchen and we accidently brought you the wrong sandwich, and we need it for somebody else..." I don't remember exactly what I said, but I didn't let her take back the sandwich. Maybe if she had been as cute as Grover, I might have allowed it. But come on...what if I had already taken a bite out of it, or sneezed on it or something? If I were the other patron, I wouldn't want a sandwich that they'd given to someone else first, and I suspect that that might even violate some health code.
Needless to say, I've never gone back there, and I don't intend to.
