I've had a similar thing recently, but not with an agency with a parlour. I phoned up on Saturday afternoon, asking what time they closed (it wasn't listed on their website) and was told 4:30pm - a time when most men haven't even finished work, if they are at work. Seems like they are losing a lot of potential business. So, it's not the same circumstances as Anth, but I was left wondering the same thing: why they don't want the business.
And no I didn't visit as I called at 3pm and wasn't ready.
