They're just as bad as the rest of Royal Mail, a terrible service run by idiots and staffed by jumped up prats who think they're far higher status than the bloody till jockeys that they are.
It took half an hour for me to get from one end of the queue to another just to send my sister her birthday present (already belated by late delivery to me). This comes after the stunning ideas of closing most of the other city center Post Offices, and of reducing the number of tellers in the remaining main Post Office.
The guy serving try to sell me more expensive delivery options on account of the strike, brilliant plan, totally screw up your regular deliveries in order to pimp your premium service. He then, in the face of a massive queue, didn't call the next customer but tried to sell me a new credit card. If I wanted to get another credit card I'd ask, I don't want to get delayed any further because everyone and their dog is getting offered all sorts of services they didn't come in for.
Quick tip post office, if you want to make money improve your basic service rather than trying to hawk crap.
