I cannot keep this rule

When I went to restaurant with my wife for taking dinner together I ordered beer then I was asked by waiter, “You don’t drive a car, do you?” I always answered, “Absolutely, I don’t drive after drinking an alcohol.” But then, a waiter asked me, “You don’t drive a car and a bicycle, do you?”

Me: Bicycle…!?

Then I said to him, “Why I can’t ride on a bicycle after drinking a beer? Bicycle haven’t got an engine!!” and I said “I might ride on a bicycle after drinking a beer.”

To begin with, I’m obliged to ride a bicycle when I drink an alcohol because of prohibition driving an automobile nevertheless I can’t ride a bicycle.

I never acknowledge and I’ll use a bicycle after drinking an alcohol.

I want to complain to a person who made a decision this crazy rule. “I wonder why you don’t decide to prohibit a drinking alcohol in itself.”
