If I ask for a deposit, these are the circumstances and the why I feel it's warranted.
If they " no showed" on the past appt and want to book again. I ask for a 25% deposit.
(Self explanatory for why)
If its for more than an hour sesh. (I don't typically have first time clients asking for 2 hr+ sessions. Its my way of feeling out the legitimacy of their appt)
If its over 4 hrs since the time of booking (this is for new clients because men are pretty in the moment. Sometimes the moment gets handled and they no longer feel the need)
If they want early bird appt. Reason, if Im waking up at 5 am to get ready for you and you don't show, I'm a little cranky.
Any over night appt and out of town appts. (Self explanatory)
