If I ever go to Wimbledon I would take my own picnic and maybe treat myself to the traditional Wimbledon strawberries and cream.  Probably the food and drink prices would be high but the price of strawberries and cream has remained the same since 2010 at £2.50 and perhaps it is the only thing on a menu anywhere that has not risen in the last 15 years.  Meanwhile we had strawberries and cream while watching Brits play very exciting tennis matches on television.
