I get guys phoning and texting me at 6, 7 or 8am in the morning. Ok my phone isn't officially on but I sometimes use it as my alarm clock. I used to answer politely, however have learned not to. It's usually men staying either in town in rooms over pubs - which are not discrete and often have main doors/gates to get through, or out on the M6 at truck stops, and even sometimes at the other end of the county and they want me to visit NOW. I don't usually see anyone before 10am and I certainly need notice to get ready and actually travel. Often the pubs are described as my 'hotel', but there is no way I'm visiting and certainly not that time of the morning. Occasionally it's even been two guys who are working away together who want me.
Not my style at all.
I've also learned most of the 10pm-1pm calls are to the back end of beyond, once again NOW. It's not happening, I do things mornings, and often have bookings lined up the next day so seeing anyone into the small hours isn't sensible and is going to impinge on my next day.
I will add that whenever I've tried to be polite and helpful with late or very early morning enquiries, 9 times out of 10 it's bitten me on the bum in the form of repeated texts or constant calls trying to 'persuade' me not understanding why I won't or can't charge out at that time.
