Not really a moan as they seem to be under enormous pressure. I had to go there today to try and sort out a problem for someone; room was packed and was told at least a 4 hour wait. No idea how typical that is. There are no toilets there or drink facilities in the building, so if you have to go - be prepared. I'm waiting for a call back from CAB Trowbridge and will try and sort it out that way.
