So he's shown you he has 180 out of the 400 he withdrew (is that right) so he got rid of 220. He "lost" about 100 of that on the way home. So he spent about 120 in the Griffin on some rounds of spirits, two private dances for himself (probably 40 quid) and one each for his mates. How many mates were there?
If there were two mates, that'd be 80, with some rounds of drinks it could reach 120.
Three queries though;
Losing about 100 quid on the way home is rather unfortunate, and rather unlikely.
If he only spent 120 in there, how come he felt the need to go to the cash point twice, taking out 200 each time.
How do you know for sure the 180 (?) he showed you in his wallet is from the original 400 for sure. He seems to be v happy dipping into your joint savings.
On the main topic; he's now taken 800 quid out of your joint savings - which was supposed to be for a house deposit for your family (and he's so down in the mouth about not having bought a house, right - he had to compensate by flashing the cash and buying his mates drinks and private strips 
) .... without your permission, or even consulting you.
He's also blatantly lying about the lack of nudity in the private dances (club and reviews say even public/stage dances are nude, and private dances never feature less nudity than stage dances), through his teeth, in the most ridiculous, immature, irritating manner. As I said it's like he's drawn his line in the sand and had to stick to it, even as every bit of evidence a d common sense points to it not being true.
He just comes across as such a general all round asshole, twat etc; and so selfish and irresponsible.
His mates sound like c*nts too. Their poor partners.
