Try flying in Northern Ireland and getting a transit through Aldergrove airspace at 2000 feet VFR, usual response is "negative, remain outside controlled airspace, basic service only". If the radio traffic levels are very quiet (usually) and you ask for a delay time or a reason, a typical response is "inbound Easyjet 50 miles to run 3000 feet above you, you wouldn't be separated if I let you through the zone!"
Simple solution, turn transponder off and fly right round the line on the map.
