As a supplier to retailers ourselves, you have to question the business model of some of these retailers that have gone bust after the economy has dipped for only a few months - they were so highly dependent on the banks that a 3% dip in turnover has sent them over the edge. Some of them will go bust in January and open up the next day with the same management in the same premises and the general public will often been unaware. Past Times are one of these that stuffed us for £12,000 last year.
However, in football, the authorities have quite rightly tried to make sure that administration is not the easy option it used to be - the actions of Leeds prompted this. When Ipswich, Leicester, etc. went bust they recovered pretty quickly, but the penalties inflicted on Luton, Bournemouth, Rotherham, etc. prove that this is the least palatable option nowadays.
The point is, with a retailer you can just close down and the people involved can start another business if they so wish. You can't just close down Saints and start up the next day in the Championship - it will be the Wessex league, if you are lucky.
