This is now the third thread either devoted to this subject or as in the Fans Forum thread one of the topics discussed, and seems to be the cause of mainly confusion.
First PB said the saving from taking the travel subsidy off Seagull Travel was a 6 figure sum, so probably some way off the million being quoted.
Secondly, most are baffled by the second subsidy situation, it seems to me that he is referring to the free door to door parking enjoyed by ST travelers. So to add a subsidy for travel and provide free parking, is seen as the double subsidy. Others travelling door to door by car or taxi have to pay for their parking or private hire cost with no subsidy, which maybe their choice but PB says is unfair if ST, another private hire company, receive two subsidies. Therefore ST had their travel subsidy withdrawn for the first time this season, but still receive the privilege of free parking next to the ground.
I think you are way off the mark. The double subsidy refers to the free travel zone. So anyone who lives outside the zone can pay for their own travel upto the zone and then benefit from the free travel. eg, if you live in Crawley, you travel to Haywards Heath and start the free travel. The double subsidy is that the club are paying this to the bus companies or rail companies and then they are paying it again to ST.
It would seem that the solution would be to take out the number of ST customers and deduct them from any formula that is part of the contract with Brighton Buses and/or Southern/Thameslink however, what we don't know is what formula is used to calculate the subsidy as part of the contract and how long that contract might be for!
