How much can you earn in an evening job?

[hercules1]

In outer London, say working in a pub or the like? Dh needs an evening job to bring in some money whilst studying in the day and doing school runs etc. Anyone any idea of how much he could take home in a month?

its usually minimum wage here for pubs but could be different in london and expect to do about 20 hours a week. tips vary but on weekends i would get about £5 a shift in tips etc.
