My 1st ever live cash game was at cin cins a few week back a 1 / 1 / 2 NL game.
I wasn't sure of the etiquette regarding leaving so at 12:00 I asked the question and was told 1/2 hr notice would be fine so I just said then that I'd be leaving at 1am (earlier if I lost the lot)

Sure I must have made some other etiquette errors but nothing was said so it could not have been anything major.
I'll be having a go at the £50 freeze in the Stanley at the weekend. Could end up dealing for the 1st time - now that should be interesting
