Staggers, You been teaching other landlords your tricks?
TBH, When I worked the pub/retaurant game these were the sort of jobs we expected Bar staff to do(except maybe changing barrels). I'd also add cleaning all optics, mirrors behind the bar, empty and clean the fridges etc. You aren't just there to serve the drinks you know. As for landlords not helping you there is a lot more to running a pub than most people think. I did it for nearly 8 years and unless its my last option I won't be going back thanks. When a landlord pays you to work it is costing them money out of their pocket. In this case if I was paying someone to do that work I too would make the most of the time. It is a long time since a landlord could afford to pay someone to run the pub 7 days a week without doing any of the work themselves.
