I know what you mean, but I find that if, for example you're playing on the high street, play for too long and the shopkeepers get pissed off and tell you to move on. Stay anyway, and you're being impolite and besides they might react badly- police, bucket of water thrown at instrument etc... Move on any hour and you'll actually be welcome if you turn up the day after. Still, it does depend on how many decent pitches are around and how much competition there is. Meh, maybe I'll try sticking to the one pitch for longer for the next week or so and see if it makes a difference.
