Sorry you have had to pack in a job that you enjoyed,but you have just summed up what happening in most sams houses,i have three near me and all the long term bar staff have gone to be replaced by young people who are in higher education, they only do a few hours a week and they do not stay long,so the bar staff are constantly changing,you never seem to get to know them, part of having a good local is getting to know the staff and them you,i do hope you find a job that you enjoy doing, but your best out of it as you say you left for your own sanity.
