I live in London and have seen Warwickshire at 2 Middlesex outgrounds now, Uxbridge and Radlett, plus I have been to Old Deer Park in Richmond to see other Middlesex games. No way are they laying out 100K for these fixtures. It seems to be four things they get in i) Portable toilets ii) Small stands and tents iii) An immense stack of foldable chairs with the understanding you bring your own if you don't like hard plastic iv) Catering vans or mobile bars, at it's best and most rudimentary, at Richmond, an old enamel bath filled with ice with 100s of cans in it. One thing I don't know, Uxbridge and Richmond have big bars or pavilions and can handle a big crowd, it might be the Warks ground don't have. But it's not a deal breaker. Admittedly I haven't thought about parking, that might be different in London, and I don't know how much those four things cost, but there is an income against those things as well...
