IF the customer service at Doncaster was as described, then the Management deserve to have it exposed on an internet forum! IF the service is so bad, the management should have known that and should have taken the appropriate action to remedy the problem.
The other view is that it is the customer having a bad day and security personnel are easy game in that situation. It is always good to have both sides of the story!
Alternatively, try Humberside or EMA or Leeds. Of course you could always have a similar experience but customers can vote with their feet!
