If it took me 24 hours to reply back to someone, I had better be laying in a ditch somewhere. I don't even have a Smart phone but I do have email and always get back to an inquiry either within a few minutes but never more than 3-4 hours, unless it's hair day lol then it could be up to 6 hours.
RB-I have fellas book in advance from a week to a months time all of the time.
