I do try to answer all emails at least once a day.At times because of other obligations I cannot get to MY computer.If I feel that a email is stupid,too exsplict,just plain dumb, or out of the ordinary I just don't even bother and I have better things to do with my time.
I do not do same day dates unless I have seen that person and if I do have the time.I tend to book up to 2-4 weeks in advance and definatly try not to break the date.
And if someone dose not give me the right info,I ask for it.I do not want to go around and around for info.Like I said I have better things to do with my time.If u cannot give me the info u get ignored.
