My DH goes out 2 to 3 nights every week "marketing". This is his word for going out with clients and getting pissed. It drives me mental because he comes home late, totally sozzled and falls into bed half-clothed and snores. He says it is essential to him getting ahead and that he hates it but that it is an essential part of his job. He says he has to drink when he goes out because that is what is required. He does have a high pressure job in the City and says that this is the norm there but I am very doubtful. He spends about £400 a month "marketing" and generally he cannot claim this back on expenses.
