Depends, one of our home business is a pet sitting business, and the bulk of our income from it is coming from drop ins.  We can't turn down a 3 a day drop in for a week as it is a few hundred dollar pay out.  At the same time, having to constantly drop i, and then running errands and taking care of our business, by the time I do get free time, it is like 30-40 mins, and for a detailed response, its not enough time.  So add in the having to stop, then come back, recapture my train of thought and where I was going with the post, it turns what is already an inefficient writing process even more so.  Instead of getting three or four responses a day, I get one done, if that.  It drags my response time down something fierce.  At the same time, I got ta pay the bills.
