I'm a student so I can rarely do weekday bookings until after 6pm. I say this on my profile.
One guy - "I've booked a hotel on Tuesday, what's your timetable like."
"I finish at 6 on Tuesday."
"Surely that's not all the way from the morning!"
"No, my first lecture is at 1 but it's very difficult for me to fit in bookings in the morning as I am outcalls only and have to compensate for travel, showering, changing into something more appropriate for uni, and making my way to uni on time."
"How about 9? That's gives you plenty of time."
"I have an appointment with the bank at 10."
"How about 11 then?"
"Appointments tend to last an hour and may overrun, that gives me no time to get to your hotel."
"Can't you just miss a lecture?"

I swear to god, can these people get the hint that when I say WEEKDAY EVENINGS AND WEEKENDS ONLY, I bloody mean it. I don't just say I'm a student for the sake of it, I actually bloody am and I'm not going to risk my education to do the job I'm using to pay for my education!!
