Drink please

One day a guy comes rushing up to the bar in a pub and says, "quick, Bartender, give me a tall glass of whiskey".
"Whoa" the Bartender says, "why don't we start with a shot"? The guy says, "okay, quick, some whiskey please". The Bartender pours a shot and the guy slams it. "Quick, another one please" the guy asks. The Bartender pours another one and the guy slams that. "Quick, more please" the guys says. The Bartender says, "okay, you can have your glass of whiskey, but I gotta ask, what's the occasion"? The guys says, "I just had the worst experience of my life in your bathroom. Some guy broke into my stall, held a gun to my head and said if I didn't give him a blow job, he'd blow my brains out"! "That's terrible" the Bartenders says, "what happened"? The guy says, "you didn't hear a gun shot did you"?
