I've been asked to provide a pop up tearoom-style service at our local community centre open day which is opposite my cafe.
They've suggested a fee based on a % of turnover on the day; but I have no idea what a reasonable % would be, and can't find anything online - any ideas?
I will benefit from their advertising and it will give me increased exposure to the users of the Centre - but I'm looking for some guidance on where to start from in terms of negotiating.
