I don't think that it's rushing a client to expect them to stay roughly within the hour. If you're a hard-ass about it, that would be cold. However the ones who will take the piss are the ones who need you to be a hard ass and you don't want to see again, anyway.
I have to work rather limited hours, on weekdays, and there seem to be a couple of peak times where a LOT of people want to be seen within a narrow time frame. It's hard enough to pick which ones to see and then try to gently maneuver them into time slots where they aren't inconvenienced or made to wait around, while leaving enough time in between for everything to be fresh and relaxed for them.
Most of them are happy to be on their way, anyway. I don't think anyone ever feels rushed. But I don't think that being conscious of the time when there's another appointment due is at all cold.
And, sure... if nobody is due and I'm enjoying their company, I will just hang out with no thought for the clock.
But it's not one extreme or the other.
I agree that its fair to expect clients to be in and away within the time they have paid for BUT getting your knickers in a twist over a matter of minutes so a client can shower is really quite bad IMO, They WILLL pick up on feeling rushed.
Some men are happy to leave well before they're time. I have a few clients who loose all desire once they have came first time and they do all the talking before any sex so once sex is over they jump up and start getting dressed but others like to relax and spend the time with you that they have paid good money for.
If you can manage to get them into the shower within they're time, great but if not is it really too much for them to ask/expect?
Weather your very limited time wise or not a few minutes is not the end of the world.
As I have said many times lately on here, whenever I have anything negative to say about a client, its only ever aimed at the ones who have treated me badly weather that's in person or in a text/email or phone call so I hold my hands up when I say that if I have a client who is horrible to me like I had the other week in Belfast, the guy totally abused me, I was desperate for him to leave and he took a while in the shower where I was completely pissed off cause I just wanted rid of him then to get in the shower myself, scrub myself, have a wee cry and try to shake it off before my next client was due BUT when it comes to your good clients and the ones who treat you with respect, you shouldn't grudge them a few minutes to shower cause they are your bread and butter at the end of the day.
This is just my opinion though, others may disagree.
