I was queueing at the counter being a very well-dressed elderly woman who was clearly ESL - I would guess at Japanese - who had just paid for a postcard and asked for directions to the Post Office.
The clerk told her she could send her card via DHL from the shop. Fair enough.
Except she made it clear that she didn't need a courier service, just an airmail stamp, and could he direct her to the post office.
This is where the Bad Service started. The clerk insisted - in VERY - LOUD - SIMPLE - ENGLISH - that DHL was exactly the same service as the Post Office, at the same price. No matter how firmly she insisted - politely - that she only needed directions, he refused to answer her. Or to admit that the courier service would cost 10 times as much as a stamp.
At the point where he started to fill in an Airway form, and I was about to interrupt and give her directions myself ("that door, turn right, 20 feet") - her friend rescued her, having found the Post Office himself.
Are Rymans staff on commission? And how many visitors to London are they successfully fleecing in this way?
