I met the owner/manager/whatever for a chat one evening as I was interested in hiring the venue for our wedding lunch. He really had a high opinion of himself and his establishment. There was no way I could work with him; total up-his-arse knob. I appreciate managers come and go so to avoid...
I have done a few times but it depends on the establishment and the circumstances. A new place finding it's way with enthusiastic people will get a different response to a **** up than, say, the up-his-arse arrogant fool who ran Due South (god that bloke annoyed me)
