You do need a license to sell stuff - and they do crack down periodically. But it`s more of a once a week sort of thing. Go around, fine everybody, then ignore for the next week.

Unless you`re in prime territory, like right in front of the exit of a very busy station. They`ll get you quick there as it`s actually getting in the way. Otherwise unless it becomes a "nuisance" there is no reason.

Performers don`t need a permit unless they set up an actual stage. They`ll be told to move if they`re in the way, but that`s about it.
