I was the GM trying to introduce a new character in a game of Flashing Blades (roleplaying in Paris in the time of the musketeers). I arranged that the group was trying to find a contact in the secret organization. Both the original party and the new PC had signs and countersigns. They were supposed to meet in a tavern.

The new PC started by trying to pick the pocket of a wealthy-looking gentleman, who, as it happened, was a PC. He got caught, they fought, and they chased him out of the tavern. Then they tried to make their contact - whom they had just run off.

Every time the new PC tried to get back into the tavern so he could meet up with them, the group threw him out - through the window, and then went back to annoying the other patrons and trying to find their contact, whom they had just defenestrated.

They eventually annoyed one drunk man enough that they got into a duel, which their guy lost. (They were convinced he could beat any drunk fencer. Yes, the guy was drunk. He was also Athos.)

Only after Athos had wounded their best fencer, and still wouldn't respond to their code words, was the would-be pickpocket able to sneak up and give the countersign without being attacked.
