"Treacherous" is a word in ENGLISH

An armless man walked into a bar which is empty except for the bartender. He ordered a drink and when he was served, asked the bartender if he would get the money from his wallet in his pocket, since he has no arms. The bartender obliged him. He then asked if the bartender would tip the glass to his lips. The bartender did this until the man finished his drink. He then asked if the bartender would get a hanky from his pocket and wipe the foam from his lips. The bartender did it and commented it must be very difficult not to have arms and have to ask someone to do nearly everything for him. The man said, "Yes, it is a bit embarrassing at times. By the way, where is your restroom?" The bartender quickly replies -, "The closest one is in the gas station three blocks down the street."
