Seriously? You do realise she's a hoor right? How long do you think it takes to clean a fanny? 20 secs max, or do you think they spend hours preening themselves after every customer then sitting around trying to look gorgeous before you turn up
When you go for a haircut at a busy barber do you complain that there's a guy in the chair already and a queue behind you?
Every booking is 'back to back'. what does the time between them matter if she give you a good service?
Issues are...
when she is down to 1-2 minutes between punts is she washing her fanny ?
are you going to get your 'full time' - shower will be in 'paid' time,
more of a rushed service so you cum and go quick because someone is waiting
previous guy is likely to see you 'loitering'
nest guy is likely to see you leaving,
both of which increase the risk of coming into contact with some mental stalker / blackmailer
And all so she can squeeze in an extra 1 or 2 punters a day rather than starting or finishing an hour earlier or later.
No matter how good she is, the above means I will take my money elsewhere.
