I'm a self employed Landscaper, so if I'm working locally I can basically attend whatever I wish, however you learn very quickly if you do this every time the pager goes off you soon run out of money, as you don't get paid till the jobs finished. Never had a problem either with clients, they have always been very understanding. So I've got to the stage now if I can see the smoke or the pager keeps going off for more crew, I'll attend whilst I'm working or if a get a sms from the wife (who's also a firie) saying get your butt down here.
