<human>: My first real job when I was 16/17 was in a small but very popular restaurant in my town in Ireland.  

One busy Saturday night I had a particularly obnoxious table. This is a small town so everyone knows everyone and despite these arseholes having a very big opinion of themselves and their own importance, they're fairly well renowned for being gobshites.  

Having had a couple of unpleasant interactions with them (one of the ladies loudly attempting to tear me a new one for "lying to her" about the soup being vegetarian when it was "clearly made with chicken stock" - it wasn't, all their soups are vegetarian and gluten free to this day), I was tending to another table when one of the men whistled at me from across the room. 

Not a discreet raise of the hand or "excuse me", but a full on high pitched whistle as though he were beckoning his dog from across a field.

The restaurant hushes as everyone turns to stare at this guy and on the table beside this clown, my boss, the owner, who happened to be enjoying dinner with his boyfriend that evening and had been watching the antics of this table since they arrived, gently stands up and in front of the packed restaurant (and plenty of people who would know or have business with these arseholes), calmly tells them that his staff are not dogs and will not be treated as such. Then that the starters are on the house but they will not be served anything else this evening and are free to leave his restaurant.

They start mumbling apologies but he holds firm and the whistler starts shouting insults about a proper business man not turning away business on a Saturday night. They eventually leave with pretty much the entire restaurant staring at them but just before they reach the door, some joker at a table full of (fairly drunk) guys loudly wolf whistles at them and the whole place breaks down laughing.

To top it all off, as I opened the door and wished them good night, I got to enjoy their faces as they saw the queue of 10 or so people outside and hear me tell the first group that if they could bear with me for a couple of minutes, a table had just become available.

<bot>: Arsehole whistles at server in front of packed restaurant. Owner sitting at next table kicks him out and other customer wolf whistles arsehole as he is walk of shaming it out.
