1. Remain calm
There is no need to panic, doing so will only make him more aggressive. You don’t want to cause a scene and make him think you’re just shocked and amazed by his coin tricks. Remain calm and make sure that you are able to formulate an exit strategy.
2. Avoid eye contact
Eye contact will come off as a challenge and you don’t want to seem like you are engaging in any way. If he holds a card in front of your face and screams “get a good look at this card and remember it!” do everything you can to avoid actually looking at the card. Close your eyes if you have to. Avoid looking at him directly as you find a way out of the situation.
3. Stand tall
Chances are he is more afraid of you than you are of him. Stand your ground and make sure to stand up straight. This will intimidate him and could scare him off if he’s not too aggressive. Chances are he’s not used to being around non-magicians and he could get scared and leave you alone.
4. Make lots of noise
This will confuse him and while he’s distracted you might be able to find a way to escape unscathed. He could get startled and drop his cards and while he’s picking them up one by one you can make a break.
5. Back away slowly
Running will only cause a chase and you don’t want that. Instead, try to put as much distance between you and the man as possible by slowly backing up so he doesn’t notice you’re moving. Back away slowly and be careful not to make any sudden movements so he does not notice while he’s setting up his cups and balls on a table. Hopefully, by the time he’s set up you will already be far enough away that you can escape safely.
6. Play dead
This is a last resort. If all other attempts to exit the situation fail, lay on the ground and play dead. Most likely he will no longer see you as a target and will move on to someone else.
