Only the first minutes of this excellent episode, are so exquisite. An old man gets out of a bank as a common customer. But after five hundred meters, he stops walking and totally changes suits, a real transformation. We discover in the next shot that he robbed the bank. Then the new man after transformation gets back home as a regular family man. He finds his wife with a lady friend of hers and then explains that he works in the bank business. Later, with friends of his visiting him at home, he "jokes" with them and presents him as a bank robber; of course everybody laughs...He continues with golf friends joking about himself as he did previously. This is typically British, tongue in cheek, very well done. I don't think the Americans could do the same. i won't spoil this episode any further, but you can trust me.
